Enum SecretboxError 

pub enum SecretboxError {
    Truncated,
    TagMismatch,
    Random(RandomError),
}

crypto_secretbox can fail for reasons beyond a wrong key.

Variants

Truncated

The input to open is shorter than a nonce plus a tag (48 bytes) - too short to have ever been produced by seal.

TagMismatch

Authentication failed: wrong key, or sealed was tampered with.

Random(RandomError)

The OS CSPRNG failed while generating a nonce (see crate::randombytes).

Trait Implementations

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
