deriveKey
fun deriveKey(algorithm: Algorithm, ikm: ByteArray, salt: ByteArray?, info: ByteArray, length: Int): ByteArray
Derives a symmetric encryption key according to HKDF as defined by RFC 5869.
Return
output keying material of length octets.
Parameters
algorithm
the KDF algorithm to use e.g. Algorithm.HMAC_SHA256.
ikm
input key material.
salt
optional salt value (a non-secret random value).
info
context and application specific information (can be zero-length).
length
length of output keying material in octets.
