Enum sequoia_openpgp::types::SymmetricAlgorithm [−][src]
#[non_exhaustive] pub enum SymmetricAlgorithm { }
The symmetric-key algorithms as defined in Section 9.2 of RFC 4880.
The values can be converted into and from their corresponding values of the serialized format.
Use SymmetricAlgorithm::from
to translate a numeric value to a
symbolic one.
Note: This enum cannot be exhaustively matched to allow future extensions.
Examples
Use SymmetricAlgorithm
to set the preferred symmetric algorithms on a signature:
use sequoia_openpgp as openpgp; use openpgp::packet::signature::SignatureBuilder; use openpgp::types::{HashAlgorithm, SymmetricAlgorithm, SignatureType}; let mut builder = SignatureBuilder::new(SignatureType::DirectKey) .set_hash_algo(HashAlgorithm::SHA512) .set_preferred_symmetric_algorithms(vec![ SymmetricAlgorithm::AES256, ])?;
Variants (Non-exhaustive)
Null encryption.
IDEA block cipher.
3-DES in EDE configuration.
CAST5/CAST128 block cipher.
Schneier et.al. Blowfish block cipher.
10-round AES.
12-round AES.
14-round AES.
Twofish block cipher.
18 rounds of NESSIEs Camellia.
24 rounds of NESSIEs Camellia w/192 bit keys.
24 rounds of NESSIEs Camellia w/256 bit keys.
Private(u8)
Private algorithm identifier.
Unknown(u8)
Unknown algorithm identifier.
Implementations
impl SymmetricAlgorithm
[src]
impl SymmetricAlgorithm
[src]pub fn is_supported(&self) -> bool
[src]
pub fn is_supported(&self) -> bool
[src]Returns whether this algorithm is supported by the crypto backend.
All backends support all the AES variants.
Examples
use sequoia_openpgp as openpgp; use openpgp::types::SymmetricAlgorithm; assert!(SymmetricAlgorithm::AES256.is_supported()); assert!(SymmetricAlgorithm::TripleDES.is_supported()); assert!(!SymmetricAlgorithm::IDEA.is_supported()); assert!(!SymmetricAlgorithm::Unencrypted.is_supported()); assert!(!SymmetricAlgorithm::Private(101).is_supported());
pub fn key_size(self) -> Result<usize>
[src]
pub fn key_size(self) -> Result<usize>
[src]Length of a key for this algorithm in bytes. Fails if Sequoia does not support this algorithm.
pub fn block_size(self) -> Result<usize>
[src]
pub fn block_size(self) -> Result<usize>
[src]Length of a block for this algorithm in bytes. Fails if Sequoia does not support this algorithm.
