Implementations

impl DataEncryptionAlgorithm

pub const fn is_authenticated(self) -> bool

Whether successful decryption cryptographically authenticates the key.

pub const fn key_kind(self) -> SymmetricKeyKind

Key family required independently of the byte length (AES-192 and three-key Triple DES both use 24 bytes).

pub fn from_uri(uri: &str) -> Result<Self, XmlEncError>

Parse a supported XMLEnc content-encryption URI.

pub const fn key_len(self) -> usize

Required symmetric key length in bytes.

pub const fn uri(self) -> &'static str

Return the standard XMLEnc algorithm URI.

pub const fn requires_explicit_permission(self) -> bool

Compile-time capability is not the operation’s permission. Whether this capability must be explicitly selected in the operation allowlist.
