Enum diem_crypto::hkdf::HkdfError [−][src]
pub enum HkdfError {
InvalidOutputLengthError,
WrongPseudorandomKeyError,
MACKeyError,
InvalidSeedLengthError,
}
Expand description
An error type for HKDF key derivation issues.
This enum reflects there are various causes of HKDF failures, including: a) requested HKDF output size exceeds the maximum allowed or is zero. b) hash functions outputting less than 32 bits are not supported (i.e., SHA1 is not supported). c) small PRK value in HKDF-Expand according to RFC 5869. d) any other underlying HMAC error.
Variants
HKDF expand output exceeds the maximum allowed or is zero.
PRK on HKDF-Expand should not be less than the underlying hash output bits.
HMAC key related error; unlikely to happen because every key size is accepted in HMAC.
HKDF extract input seed should not be less than the minimum accepted.
