Struct PkeyEncryptCtx 

pub struct PkeyEncryptCtx { /* private fields */ }

RSA asymmetric encryption context.

Implementations

impl PkeyEncryptCtx

pub fn new( key: &Pkey<Public>, params: Option<&Params<'_>>, ) -> Result<Self, ErrorStack>

Create an encryption context from a public key.

params is applied immediately after init if Some. Typical use:

let oaep = ParamBuilder::new()?.push_utf8_string(c"pad-mode", c"oaep")?.build()?;
let ctx = PkeyEncryptCtx::new(&pub_key, Some(&oaep))?;

Errors

pub fn set_params(&mut self, params: &Params<'_>) -> Result<(), ErrorStack>

Configure parameters (e.g. RSA padding mode).

Errors

pub fn encrypt( &mut self, plaintext: &[u8], ciphertext: &mut [u8], ) -> Result<usize, ErrorStack>

Encrypt plaintext into ciphertext.

Returns the number of bytes written.

Errors

pub fn encrypt_len(&mut self, plaintext_len: usize) -> Result<usize, ErrorStack>

Query the ciphertext length for a given plaintext length.

Errors
