Functions

expand

HKDF expand using hash function mode, pre-key material prk, info, and output length okm_len. Returns the key material in a vector of length okm_len or Error::OkmLengthTooLarge if the requested output length is too large.

extract

HKDF extract using hash function mode, salt, and the input key material ikm. Returns the pre-key material in a vector of tag length.

hkdf

HKDF using hash function mode, salt, input key material ikm, info, and output length okm_len. Calls extract and expand with the given input. Returns the key material in a vector of length okm_len or Error::OkmLengthTooLarge if the requested output length is too large.
