## 📦 Usage

Here are a few quick examples of how to use `aplustools`.

---

### 🔁 `auto_repr`: Auto-generate clean `__repr__`

```python
from aplustools.io.env import auto_repr

@auto_repr
class Person:
    def __init__(self, name: str, age: int, email: str):
        self.name = name
        self.age = age
        self.email = email
        self._internal = "should be hidden"

p = Person("Alice", 30, "alice@example.com")
print(p)  # Person(name=Alice, age=30, email=alice@example.com)
```

---

### 🔁 `auto_repr_with_privates`: Show private fields too

```python
from aplustools.io.env import auto_repr_with_privates

class Person:
    def __init__(self, name: str, age: int):
        self.name = name
        self._age = age  # Will be shown in __repr__

auto_repr_with_privates(Person, use_repr=True)
print(Person("Bob", 42))  # Person(name='Bob', _age=42)
```

---

## 🔐 File Locking (Cross-Platform)

### ✅ Manual file locking via `get_system()`

```python
from aplustools.io.env import get_system

fd = get_system().lock_file("test.lock", blocking=True)
print(get_system().is_file_locked("test.lock"))  # True
get_system().unlock_file(fd)
```

---

### ✅ Context-managed locking via `OSFileLock`

```python
from aplustools.io.fileio import OSFileLock

with OSFileLock("test.lock") as fd:
    print(f"Locked with fd={fd}")
# Lock is automatically released here
```

---

### ✅ Pythonic locking with `os_open` (like `open()`)

```python
from aplustools.io.fileio import os_open

with os_open("example.txt", "w") as file:
    file.write("Hello, safely locked world!\n")
```

> Internally uses `OSFileLock` for safe, exclusive access across platforms (Unix/Windows).

---

## 🔢 Binary Encoding Utilities (`aplustools.data.bintools`)

Efficient tools for working with binary formats and structured bytes.

---

### 📏 Measure bit and byte length

```python
from aplustools.data.bintools import bit_length, bytes_length

print(bit_length(42))      # 6
print(bytes_length(1000))  # 2
```

---

### 🔁 Encode/Decode integers

```python
from aplustools.data.bintools import encode_integer, decode_integer

encoded = encode_integer(123456)
print(encoded)             # b'\x01\xe2@'

decoded = decode_integer(encoded)
print(decoded)             # 123456
```

---

### 🔁 Encode/Decode floats

```python
from aplustools.data.bintools import encode_float, decode_float

f_bytes = encode_float(3.14159, precision="single")
print(decode_float(f_bytes, precision="single"))  # ~3.14159
```

---

### 📦 Variable-length integer encoding

```python
from aplustools.data.bintools import to_varint_length, read_varint_length
import io

data = to_varint_length(300)
length = read_varint_length(io.BytesIO(data))
print(length)  # 300
```

---

### 📏 Human-readable size formatting

```python
from aplustools.data.bintools import bytes_to_human_readable_binary_iec

print(bytes_to_human_readable_binary_iec(1024))      # 1.0 KiB
print(bytes_to_human_readable_binary_iec(1048576))   # 1.0 MiB
```

---

## 🔐 Secure Password Generation (`aplustools.security.passwords`)

Create readable, secure, and crack-resistant passwords.

---

### 🔑 Generate secure passwords easily

```python
from aplustools.security.passwords import SecurePasswordGenerator

generator = SecurePasswordGenerator(security="super_strong")
pw_data = generator.passphrase()

print(pw_data["password"])     # Actual password
print(pw_data["extra_info"])   # Generation method metadata
```

---

### 🔧 Available styles

```python
generator.sentence()         # Readable sentence
generator.pattern()          # Format like Aa99##
generator.complex_pattern()  # Pattern + random word mix
generator.complex()          # High entropy, mixed format
generator.mnemonic()         # Easy to remember
```

---

### 🧠 Estimate worst-case crack time

```python
pw_data = generator.generate_secure_password(return_worst_case=True)
print(pw_data["worst_case"])  # e.g., "centuries"
```

---

## ⏱ Basic Timing (`aplustools.package.chronokit`)

Measure elapsed time with nanosecond resolution.

---

### ⏲ Use `BasicTimer` for simple measurements

```python
from aplustools.package.chronokit import BasicTimer
import time

timer = BasicTimer(auto_start=True)
time.sleep(0.123)
timer.stop()

print(timer.get())          # timedelta
print(timer.get_readable()) # Human-readable
```

---

### 📏 Create precise deltas

```python
from aplustools.package.chronokit import PreciseTimeDelta

delta = PreciseTimeDelta(seconds=1.5, microseconds=250)
print(str(delta))           # 0:00:01.500250
print(delta.to_readable())  # "1.500s"
```

---

## ⏱ Flexible Timing with `FlexTimer`

Advanced control for performance tracking, interval measurements, and benchmarking.

---

### 🧪 Measure CPU-only time (ignores sleep)

```python
from aplustools.package.chronokit import CPUFTimer

with CPUFTimer():
    sum(i * i for i in range(100_000))
```

> Ideal for benchmarking with minimal system interference.

---

### 🔄 Manual start/stop and waiting

```python
from aplustools.package.chronokit import FlexTimer

t = FlexTimer(start_now=False)
t.start(start_at=1.2)
t.wait(0.8)
t.stop()

print(t.get().to_clock_string())  # e.g., 00:00:02.00
```

---

### ⏱ Record laps (interval checkpoints)

```python
t = FlexTimer()
# ... task 1 ...
t.lap()
# ... task 2 ...
t.lap()

print(t.show_laps())  # List of lap durations
```

---

### 🪄 Time entire functions with a decorator

```python
@FlexTimer().time()
def compute():
    return [x**2 for x in range(1_000_000)]

compute()  # Prints execution time
```

---

### 🕒 Schedule callbacks after a delay

```python
def on_done():
    print("Finished!")

FlexTimer().after(2, on_done)
```

---

### 🧵 Run functions at intervals

```python
def tick():
    print("Tick!")

FlexTimer().interval(1, count=5, callback=tick)
```

---

### 📈 Estimate time complexity of a function

```python
def fn(n):
    return [i ** 2 for i in range(n)]

def gen_inputs():
    for i in range(1000, 50000, 1000):
        yield ((i,), {})

from aplustools.package.chronokit import FlexTimer
print(FlexTimer.complexity(fn, gen_inputs()))  # e.g., "O(N)"
```

---

## ⚙️ Concurrency and Shared Memory (`aplustools.io.concurrency`)

Smart thread pools and safe process-shared memory.

---

### 🧵 Dynamic thread pool with auto-scaling

```python
from aplustools.io.concurrency import LazyDynamicThreadPoolExecutor
import time

def task(i):
    time.sleep(0.5)
    return f"Task {i}"

with LazyDynamicThreadPoolExecutor(min_workers=2, max_workers=10) as pool:
    results = [f.result() for f in [pool.submit(task, i) for i in range(5)]]

print(results)
```

---

### 🧠 Share memory across processes with `SharedStruct`

```python
from aplustools.io.concurrency import SharedStruct
from multiprocessing import Process

def increment(ref, count):
    shared = ref.dereference()
    for _ in range(count):
        with shared:
            val = shared.get_field(0)
            shared.set_field(0, val + 1)
    shared.close()

if __name__ == "__main__":
    counter = SharedStruct("i", create=True)
    counter.set_field(0, 0)

    p1 = Process(target=increment, args=(counter.reference(), 1000))
    p2 = Process(target=increment, args=(counter.reference(), 1000))
    p1.start(); p2.start(); p1.join(); p2.join()

    print("Final:", counter.get_field(0))  # 2000
    counter.close()
    counter.unlink()
```

---

### 📎 Struct format reference

* `"i"` — one 4-byte integer
* `"if"` — integer + float
* `"i10s"` — integer + 10-byte string

```python
with SharedStruct("if", create=True) as stats:
    stats.set_data(42, 3.14)
    print(stats.get_data())  # (42, 3.14)
```

---

## 🌐 Web Requests (`aplustools.web.request`)

Make web requests in sync or async mode — single or batch.

---

### 🔹 Quick HTTPS fetch

```python
from aplustools.web.request import fetch

data = fetch("https://httpbin.org/get")
print(data.decode())
```

---

### 🔸 Threaded batch requests with `BatchRequestHandler`

```python
from aplustools.web.request import BatchRequestHandler

handler = BatchRequestHandler(min_workers=2, max_workers=10)

# Single request
print(handler.request("https://httpbin.org/get").decode())

# Multiple (sync)
urls = ["https://httpbin.org/get"] * 5
print(len(handler.request_many(urls)))

# Multiple (async)
result = handler.request_many(urls, async_mode=True)
print(len(result.no_into().no_into_results))

handler.shutdown()
```

💡 The thread pool can be reused via `handler.pool`.

---

### ⚡ High-performance async requests with `AioHttpRequestHandler`

```python
from aplustools.web.request import AioHttpRequestHandler

aio = AioHttpRequestHandler()

print(aio.request("https://httpbin.org/get").decode())
print(len(aio.request_many(["https://httpbin.org/get"] * 5)))

aio.shutdown()
```

> Sync interface, but internally async. Great for sync environments that want async speed.

## 🔐 `aplustools.security.crypto`

This section demonstrates the flexible, backend-agnostic cryptography interface provided by `aplustools`. The section includes standard hashing, key derivation, and post-quantum encryption/signing using modern algorithms.

### 📦 Setup and Imports

```python
from aplustools.security.crypto.algos import (
    Sym,
    Asym,
    HashAlgorithm,
    KeyDerivationFunction,
)
from aplustools.security.crypto.exceptions import NotSupportedError
from aplustools.security.crypto import set_backend, Backend
import os
```

Set the std lib cryptography backend (you can later switch to advanced libraries like `cryptography`, `argon2-cffi`, etc.):

```python
set_backend()  # Uses Backend.std_lib
```

### 🔍 Hashing with Standard Algorithms

Most `HashAlgorithm` variants support `.hash()`, `.verify()`, and `.std_verify()`.

```python
# MD5
h = HashAlgorithm.MD5.hash(b"hello world")
print("MD5:", h.hex())
print("Verify:", HashAlgorithm.MD5.verify(b"hello world", h))
print("Std-Verify:", HashAlgorithm.std_verify(b"hello world", h))

# SHA1
h = HashAlgorithm.SHA1.hash(b"hello world")
print("SHA1:", h.hex())
print("Verify:", HashAlgorithm.SHA1.verify(b"hello world", h))
print("Std-Verify:", HashAlgorithm.std_verify(b"hello world", h))

# SHA256
h = HashAlgorithm.SHA2.SHA256.hash(b"hello world")
print("SHA256:", h.hex())
print("Verify:", HashAlgorithm.SHA2.SHA256.verify(b"hello world", h))
print("Std-Verify:", HashAlgorithm.std_verify(b"hello world", h))

# SHA3-256
h = HashAlgorithm.SHA3.SHA256.hash(b"hello world")
print("SHA3-256:", h.hex())
print("Verify:", HashAlgorithm.SHA3.SHA256.verify(b"hello world", h))
print("Std-Verify:", HashAlgorithm.std_verify(b"hello world", h))
```

### ⚖️ Hashing with Variable-Length and Specialized Algorithms

Some algorithms require an output length (e.g., SHAKE128, BLAKE2s):

```python
# SHAKE128 (8 bytes)
h = HashAlgorithm.SHA3.SHAKE128.hash(b"hello", 8)
print("SHAKE128:", h.hex())
print("Verify:", HashAlgorithm.SHA3.SHAKE128.verify(b"hello", h))
print("Std-Verify:", HashAlgorithm.std_verify(b"hello", h))

# BLAKE2s (8 bytes)
h = HashAlgorithm.BLAKE2.BLAKE2s.hash(b"hello", 8)
print("BLAKE2s:", h.hex())
print("Verify:", HashAlgorithm.BLAKE2.BLAKE2s.verify(b"hello", h))
print("Std-Verify:", HashAlgorithm.std_verify(b"hello", h))
```

Some algorithms are optional in std lib:

```python
# RIPEMD160
try:
    h = HashAlgorithm.RIPEMD160.hash(b"hello")
    print("RIPEMD160:", h.hex())
    print("Verify:", HashAlgorithm.RIPEMD160.verify(b"hello", h))
    print("Std-Verify:", HashAlgorithm.std_verify(b"hello", h))
except Exception as e:
    print("RIPEMD160 unsupported in std_lib:", e)
```

### 🔑 Key Derivation Functions (KDFs)

All KDFs support `.derive(password, salt, ...)` and produce fixed-length binary output:

```python
password = b"my-password"
salt = os.urandom(16)

print("PBKDF2HMAC:", KeyDerivationFunction.PBKDF2HMAC.derive(password, salt=salt).hex())
print("PBKDF1    :", KeyDerivationFunction.PBKDF1.derive(password, salt=salt, length=16).hex())
print("Scrypt    :", KeyDerivationFunction.Scrypt.derive(password, salt=salt, length=16).hex())
print("HKDF      :", KeyDerivationFunction.HKDF.derive(password, salt=salt).hex())
print("ConcatKDF :", KeyDerivationFunction.ConcatKDF.derive(password, otherinfo=b"my-info").hex())
```

### 🛠 Switch to Advanced Backends

Enable advanced features like post-quantum crypto and better hashing support:

```python
set_backend(
    [
        Backend.cryptography_alpha,  # Currently only supports hashes like SHA3
        Backend.quantcrypt,          # To enable post-quantum cryptography
        Backend.argon2_cffi,         # Required for Argon2
        Backend.bcrypt,              # Required for BCrypt
        Backend.std_lib,             # Fallback
    ]
)
```

### 🧂 Argon2 Hashing and Verification

```python
# Hash a password/message using Argon2
hashed = HashAlgorithm.ARGON2.hash(b"Ha", os.urandom(16))
print("\nArgon2 Hash:", hashed.decode())

# Verify the hash
is_valid = HashAlgorithm.ARGON2.verify(b"Ha", hashed)
print("Argon2 Valid:", is_valid)

try:
    print(
        "Std-Verify",
        HashAlgorithm.std_verify(
            b"Ha", hashed, fallback_algorithm="argon2", text_ids=False
        ),
    )  # Std-Verify can't decode special algos like argon2 or bcrypt
except NotSupportedError:
    print("Std-Verify failed")
```

### 🔐 BCrypt Hashing and Verification

```python
# Hash a password with BCrypt
bcrypt_hash = HashAlgorithm.BCRYPT.hash(b"my-secret-password")
print("BCrypt Hash:", bcrypt_hash.decode())

# Verify the password against the hash
is_valid = HashAlgorithm.BCRYPT.verify(b"my-secret-password", bcrypt_hash)
print("BCrypt Valid:", is_valid)
```

### 🔑 Argon2 / BCrypt for Secure Key Derivation

```python
# Derive a key using Argon2 KDF
derived_key = KeyDerivationFunction.ARGON2.derive(b"my-password", salt=os.urandom(16))
print("Argon2 Derived Key:", derived_key.hex())

# Derive a key using BCrypt KDF
bcrypt_key = KeyDerivationFunction.BCRYPT.derive(b"my-password", salt=os.urandom(16))
print("BCrypt Derived Key:", bcrypt_key.hex())
```

## 🔐 Asymmetric Encryption: Kyber (Post-Quantum KEM)

This demonstrates a Kyber key exchange using encapsulation (sender) and decapsulation (recipient):

```python
# Recipient generates a keypair
recipient_key = Asym.Cipher.KYBER.keypair.new("kyber1024")

# Extract public key from recipient and share it with the sender
pub_key_bytes = recipient_key.encode_public_key()
# Keys can't be regenerated and try: except: takes more space; 
# This can only happen if you do not pass one of the keys when using .decode( ... )
if pub_key_bytes is None:
    raise ValueError("recipient_key has no public key")

# Sender receives the public key and creates a key object with only the public key
sender_key = Asym.Cipher.KYBER.keypair.decode("kyber1024", public_key=pub_key_bytes)
# Sender encapsulates a shared secret for the recipient
ciphertext, shared_secret_sender = sender_key.encapsulate()

# Recipient decapsulates to recover the shared secret
shared_secret_recipient = recipient_key.decapsulate(ciphertext)

print("\n=== Kyber KEM Flow ===")
print(f"Ciphertext             : {ciphertext.hex()}")
print(f"Sender Shared Secret   : {shared_secret_sender.hex()}")
print(f"Recipient Shared Secret: {shared_secret_recipient.hex()}")
assert shared_secret_sender == shared_secret_recipient, "Shared secrets do not match!"
```

## ✍️ Asymmetric Signing: Dilithium (Post-Quantum Signature)

This demonstrates secure message signing and verification using the Dilithium signature algorithm:

```python
# Generate the signing keypair (private + public)
sign_key = Asym.Cipher.DILITHIUM.keypair.new("dilithium5")

# Sign a message using the private key
message = b"Hello World"
signature = sign_key.sign(message)

# Extract and share only the public key
pub_key_bytes = sign_key.encode_public_key()
# Keys can't be regenerated and try: except: takes more space; 
# This can only happen if you do not pass one of the keys when using .decode( ... )
if pub_key_bytes is None:
    raise ValueError("sign_key has no public key")

# Create a new key object with only the public key for verification
verify_key = Asym.Cipher.DILITHIUM.keypair.decode(
    "dilithium5", public_key=pub_key_bytes
)
# Verify the signature using the public key
is_valid = verify_key.sign_verify(message, signature)

print("\n=== Dilithium Signature Flow ===")
print(f"Signature     : {signature.hex()}")
print(f"Signature Valid? {is_valid}")
assert is_valid, "Signature verification failed!"
```
