Implementations

impl DecryptingKey

pub fn ctr(key: UnboundCipherKey) -> Result<DecryptingKey, Unspecified>

Constructs a cipher decrypting key operating in counter (CTR) mode using the provided key and context.

Errors

• Unspecified: Returned if there is an error during decryption.

pub fn cfb128(key: UnboundCipherKey) -> Result<Self, Unspecified>

Constructs a cipher decrypting key operating in cipher feedback 128-bit mode (CFB128) using the provided key and context.

Errors

• Unspecified: Returned if there is an error during decryption.

pub fn cbc(key: UnboundCipherKey) -> Result<DecryptingKey, Unspecified>

Constructs an DecryptingKey operating in cipher block chaining (CBC) mode using the provided key and context.

☠️ ️️️DANGER ☠️

Offered for compatibility 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 during decryption.

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

Constructs an DecryptingKey operating in electronic code book (ECB) mode using the provided key.

☠️ ️️️DANGER ☠️

Offered for compatibility 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 DecryptingKey.

fn new(key: UnboundCipherKey, mode: OperatingMode) -> Result<Self, Unspecified>

pub fn algorithm(&self) -> &Algorithm

Returns the cipher algorithm.

pub fn mode(&self) -> OperatingMode

Returns the cipher operating mode.

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

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

If DecryptingKey is operating in OperatingMode::ECB, then in_out.len() must be a multiple of the block length.

Errors

• Unspecified: Returned if cipher mode requires input to be a multiple of the block length, and in_out.len() is not. Also returned if decryption fails.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
