- Derives a key from a password using a salt and iteration count, based on PKCS#5 v2.0
- password based encryption key derivation function PBKDF2, as specified in RFC 2898.
-
- If Password or Salt or OutKey is NULL, then return FALSE.
- If the hash algorithm could not be determined, then return FALSE.
-
- @param[in] PasswordLength Length of input password in bytes.
- @param[in] Password Pointer to the array for the password.
- @param[in] SaltLength Size of the Salt in bytes.
- @param[in] Salt Pointer to the Salt.
- @param[in] IterationCount Number of iterations to perform. Its value should be
- greater than or equal to 1.
- @param[in] DigestSize Size of the message digest to be used (eg. SHA256_DIGEST_SIZE).
- NOTE: DigestSize will be used to determine the hash algorithm.
- Only SHA1_DIGEST_SIZE or SHA256_DIGEST_SIZE is supported.
- @param[in] KeyLength Size of the derived key buffer in bytes.
- @param[out] OutKey Pointer to the output derived key buffer.
-
- @retval TRUE A key was derived successfully.
- @retval FALSE One of the pointers was NULL or one of the sizes was too large.
- @retval FALSE The hash algorithm could not be determined from the digest size.
- @retval FALSE The key derivation operation failed.
