Expand description

Possible cryptographic submodule error conditions.

Variants

UnsupportedVersion(u8)

Crypto primitive uses a version this library doesn’t recognize (or one it no longer accepts).

OldVersion(u8)

Crypto primitive uses a version that’s too old, and deemed unsafe to use.

DecryptFailed

Crypto system was unable to decrypt the contents of a Lockbox.

BadLength

Fields

step: &'static str
actual: usize
expected: usize

The provided data for wasn’t the expected length.

BadKey

A provided cryptographic key (public or private) is weak or invalid.

BadFormat(&'static str)

The data format doesn’t match spec. Can occur when decoding a lockbox or attempting to decode from a String.

ObjectMismatch(&'static str)

An operation expected a specific object but didn’t get it. Eg. Signature verification expects a specific version of hash and fails if it doesn’t get a hash with that version, or a Lockbox should be unlocked with a specific key but we attempted to use the wrong one. This almost always indicates a logic error.

SignatureFailed

Verification of a signature failed.

NotSupportedByVault

The attempted operation isn’t supported by the backing Vault.
