Expand description

A cipher decryption key that performs block padding.

Implementations§

Source§

impl PaddedBlockDecryptingKey

Source

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

Constructs a new PaddedBlockDecryptingKey cipher with chaining block cipher (CBC) mode. Decrypted data is unpadded following the PKCS#7 scheme.

§Errors
  • Unspecified: Returned if there is an error constructing the PaddedBlockDecryptingKey.
Source

pub fn cbc_iso10126(key: UnboundCipherKey) -> Result<Self, Unspecified>

Constructs a new PaddedBlockDecryptingKey cipher with chaining block cipher (CBC) mode. Decrypted data is unpadded following the ISO 10126 scheme (compatible with PKCS#7 and ANSI X.923).

Offered for computability purposes only.

§Errors
  • Unspecified: Returned if there is an error constructing the PaddedBlockDecryptingKey.
Source

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

Constructs a new PaddedBlockDecryptingKey cipher with electronic code book (ECB) mode. Decrypted data is unpadded 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 the PaddedBlockDecryptingKey.
Source

pub fn algorithm(&self) -> &Algorithm

Returns the cipher algorithm.

Source

pub fn mode(&self) -> OperatingMode

Returns the cipher operating mode.

Source

pub fn decrypt<'in_out>( &self, in_out: &'in_out mut [u8], context: DecryptionContext, ) -> Result<&'in_out mut [u8], Unspecified>

Decrypts and unpads data provided in in_out in-place. Returns a references to the decrypted data.
