dd691cfa18 feat(cipher-core): add PKCS#7 padding support 
Add pkcs7_pad and pkcs7_unpad functions for block cipher modes:
    - Pad data to block size multiples with N bytes of value N
    - Validate and remove padding on decryption
    - Add InvalidPadding variant to CipherError

f4480ba218 feat(aes): add IV (Initialization Vector) type for CBC mode 
Add 128-bit IV type using secret_block! macro with:
    - Parsing from hex/binary/ASCII strings
    - Conversions to/from Block128 for XOR operations
    - Big-endian byte array conversions

2f41a0b773 docs(cipher-core): add documentation to public traits 
Document BlockCipher, InputBlock, and BlockParser with usage examples
and method descriptions. Fix incorrect error message in decrypt() that
referenced "plaintext" instead of "ciphertext".

aacb836e77 refactor(cipher-core): unify secret_block! and secret_key! macros 
Move duplicated macro definitions from aes and des crates into
cipher-core for shared use. Both macros now:
    - Support u8 through u128 integer types
    - Include Zeroize derive for secure memory handling
    - Generate consistent formatting and conversion methods

451986d702 refactor(cipher-core): extract shared block parsing logic 
Add generic BlockInt trait and parse_block_int<T>() function to
cipher-core, eliminating duplicate parsing code in aes and des crates.
    - BlockInt trait abstracts over u64/u128 integer types
    - Supports hex (0x), binary (0b), and ASCII string formats
    - Improved BlockError::InvalidByteStringLength with max/actual fields
