Description

This is a LibLoad-compatible library that contains algorithms for computing several types of hashes for files or arbitrary data segments.

Included Cryptographic Implementations:
<> SHA-1 and SHA-256.
<> Secure PRNG derived from reading bus noise into an entropy pool, passing the pool through an SHA-256, and then XORing the digest in 32-bit blocks. Evaluated entropy ~100 bits per 32 bit rand.
<> AES, CBC mode symmetric block cipher, with support for 128, 192, or 256-bit keys (replaces Blowfish in this version).
<> Base64 Encode and Decode
<> EraseContext function that can be used to erase contexts used by the various algorithms.
<> Padding helper function that can apply one of the following padding modes for AES: PKCS7, ISO Method 1, ISO Method 2, ANSIX923, or OAEP for RSA (RSA not yet implemented).

See the enclosed C header file for more details.
