pub struct Seal { /* private fields */ }
Expand description

Represents an EVP_Seal context.

Implementations

Creates a new Seal.

Returns the initialization vector, if the cipher uses one.

Returns the encrypted keys.

Feeds data from input through the cipher, writing encrypted bytes into output.

The number of bytes written to output is returned. Note that this may not be equal to the length of input.

Panics

Panics if output.len() < input.len() + block_size where block_size is the block size of the cipher (see Cipher::block_size), or if output.len() > c_int::max_value().

Finishes the encryption process, writing any remaining data to output.

The number of bytes written to output is returned.

update should not be called after this method.

Panics

Panics if output is less than the cipher’s block size.
