DecryptSemanticOutcome

Enum DecryptSemanticOutcome 

Source
pub enum DecryptSemanticOutcome {
    Success(Zeroizing<Vec<u8>>),
    AuthenticationFailed,
}
Expand description

Semantic result of an AEAD decrypt after parseable inputs were accepted.

This type is a closed enum: downstream crates cannot add variants. Use exhaustive match (or if let) to branch; do not reduce verification to a secret-derived bool without an explicit, reviewed threat model.

§Examples

use lib_q_core::{
    AeadDecryptSemantic,
    DecryptSemanticOutcome,
    AeadKey,
    Nonce,
};
match aead.decrypt_semantic(key, nonce, ct, None)? {
    DecryptSemanticOutcome::Success(pt) => {
        let _ = pt.len();
    }
    DecryptSemanticOutcome::AuthenticationFailed => {}
}

Variants§

§

Success(Zeroizing<Vec<u8>>)

Verified plaintext; buffer is zeroized on drop.

§

AuthenticationFailed

Integrity failure after the algorithm’s decrypt/verify schedule. No plaintext.
