SHA-256, HMAC-SHA-256, PBKDF2-HMAC-SHA-256
A recreational programming project that provides
Hash function: SHA-256
Hash-based message authentication tag: HMAC-SHA-256
Password-based key derivation function 2: PBKDF2-HMAC-SHA-256
Dependencies: NONE
Special properties:
HMAC & PBKDF2 require scratch buffer memory provided for them (memory use depends on length of inputs).
Memory buffer requirements:
HMAC: (64 + data length) bytes
PBKDF2: (200 + salt length) bytes
Includes small example program with references to online tests
