PBKDF1 key derivation function.
PBKDF1 applies a hash function, which shall be MD2, MD5 or SHA-1, to derive keys. The length of the derived key is bounded by the length of the hash function output, which is 16 octets for MD2 and MD5 and 20 octets for SHA-1
- Parameters:
-
[in] hash Underlying hash function (MD2, MD5 or SHA-1) [in] p Password, an octet string [in] pLen Length in octets of password [in] s Salt, an octet string [in] sLen Length in octets of salt [in] c Iteration count [out] dk Derived key [in] dkLen Intended length in octets of the derived key
- Returns:
- Error code

PBKDF2 key derivation function.
PBKDF2 applies a pseudorandom function to derive keys. The length of the derived key is essentially unbounded
- Parameters:
-
[in] hash Hash algorithm used by the underlying PRF [in] p Password, an octet string [in] pLen Length in octets of password [in] s Salt, an octet string [in] sLen Length in octets of salt [in] c Iteration count [out] dk Derived key [in] dkLen Intended length in octets of the derived key
- Returns:
- Error code
