Struct PaddedBlockEncryptingKey

pub struct PaddedBlockEncryptingKey { /* private fields */ }

A cipher encryption key that performs block padding.

Implementations

impl PaddedBlockEncryptingKey

pub fn cbc_pkcs7( key: UnboundCipherKey, ) -> Result<PaddedBlockEncryptingKey, Unspecified>

Constructs a new PaddedBlockEncryptingKey cipher with chaining block cipher (CBC) mode. Plaintext data is padded following the PKCS#7 scheme.

Errors

• Unspecified: Returned if there is an error constructing a PaddedBlockEncryptingKey.

pub fn ecb_pkcs7( key: UnboundCipherKey, ) -> Result<PaddedBlockEncryptingKey, Unspecified>

Constructs a new PaddedBlockEncryptingKey cipher with electronic code book (ECB) mode. Plaintext data is padded following the PKCS#7 scheme.

☠️ ️️️DANGER ☠️

Offered for computability purposes only. This is an extremely dangerous mode, and very likely not what you want to use.

Errors

• Unspecified: Returned if there is an error constructing a PaddedBlockEncryptingKey.

pub fn algorithm(&self) -> &Algorithm

Returns the cipher algorithm.

pub fn mode(&self) -> OperatingMode

Returns the cipher operating mode.

pub fn encrypt<InOut>( &self, in_out: &mut InOut, ) -> Result<DecryptionContext, Unspecified>

where InOut: AsMut<[u8]> + for<'a> Extend<&'a u8>,

Pads and encrypts data provided in in_out in-place. Returns a references to the encrypted data.

Errors

• Unspecified: Returned if encryption fails.

pub fn less_safe_encrypt<InOut>( &self, in_out: &mut InOut, context: EncryptionContext, ) -> Result<DecryptionContext, Unspecified>

where InOut: AsMut<[u8]> + for<'a> Extend<&'a u8>,

Pads and encrypts data provided in in_out in-place. Returns a references to the encryted data.

Errors

• Unspecified: Returned if encryption fails.
