I started the core of this project on about 2004 and since then it is being an attempt of building a tiny and straightforward

crypto library which can be easily integrated with user and also kernel mode code.

Until now these are the supported platforms:

| **Platform** | **User mode** | **Kernel mode** |

## Features

**Stream cipher**: ``ARC4``, ``SEAL``, ``RABBIT``, ``Salsa20``, ``ChaCha20``.

**Block cipher**: ``AES``, ``DES``, ``3DES``, ``3DES-EDE``, ``IDEA``, ``RC2``, ``RC5``, ``RC6``, ``FEAL``, ``CAST5``,

``Camellia``, ``SAFER-K64``, ``Blowfish``, ``Serpent``, ``TEA``, ``XTEA``, ``MISTY1``, ``MARS``, ``PRESENT``, ``SHACAL-1``,

``SHACAL-2``, ``NOEKEON``, ``GOST``, ``TWOFISH``.

**Modes of operation**: ``ECB``, ``CBC``, ``OFB``, ``CTR``, ``GCM``.

**Cryptographic hashes**: ``SHA-1``, ``SHA-224``, ``SHA-256``, ``SHA-384``, ``SHA-512``, ``MD4``, ``MD5``, ``RIPEMD-128``,

``RIPEMD-160``, ``SHA3-224``, ``SHA3-256``, ``SHA3-384``, ``SHA3-512``, ``KECCAK-224``, ``KECCAK-256``, ``KECCAK-384``,

``KECCAK-512``, ``BLAKE2s-256``, ``BLAKE2b-512``, ``BLAKE2s-N``, ``BLAKE2b-N``, ``BLAKE3``, ``Tiger``, ``Whirlpool``.

**Non-cryptographic hashes**: ``djb2`` (string hashing), ``SipHash``.

**Message authentication code**: ``HMAC``, ``Poly1305``, ``SipHash`` (recommended for short messages only),

``GCM`` (for all 128-bit block ciphers).

**PK crypto**: ``RSA``, ``RSA-OAEP``, ``El Gamal``, ``RSA-EMSA/PSS``, ``DSA``, ``ECDSA``, ``DH``, ``ECDH``.

**CSPRNG**: From the system (default one), ``Fortuna``.

**Codification stuff**: ``Base64``, ``Base32``, ``Base16``, ``UUEncode``.

**Compression stuff**: ``Huffman coding``.

**Key derivation functions**: ``HKDF``, ``PBKDF2``, ``Argon2``.

**One-time passwords**: ``HOTP``, ``TOTP``.

**Extras**: Common API between user space / kernel space (``Windows``, ``FreeBSD``, ``NetBSD`` and ``Linux``), ``RAM`` swapping

cares, data wiping when freeing memory, ``PEM`` as its common input/output (for some algorithms), convenience function macros

to make it easy to use all available cryptographic functions (``C99`` required).
