Expand description

Error type for the decoding of a SecretStorageKey.

The SecretStorageKey can be restored from a Base58 encoded string or from a string containing a passphrase.

This error type is used to report errors when trying to restore from either of those strings.

Variants§

§

Prefix([u8; 2], [u8; 2])

The decoded secret storage key has an invalid prefix.

§

Parity(u8, u8)

The parity byte of the secret storage key didn’t match.

§

Base58(Error)

The secret storage key isn’t valid Base58.

§

Base64(Base64DecodeError)

The secret storage key isn’t valid Base64.

§

KeyLength(usize, usize)

The secret storage key is too short, we couldn’t read enough data.

§

Mac(MacError)

The typed in secret storage was incorrect, the MAC check failed.

§

MacLength(usize, usize)

The MAC of the secret storage key for the MAC check has an incorrect length.

§

IvLength(usize, usize)

The IV of the secret storage key for the MAC check has an incorrect length.

§

UnsupportedAlgorithm(String)

The secret storage key is using an unsupported secret encryption algorithm. Currently only the m.secret_storage.v1.aes-hmac-sha2 algorithm is supported.

§

KdfIterationCount(UInt)

The passphrase-based secret storage key has an excessively high KDF iteration count.
