Struct Pkcs1PublicEncryptingKey

pub struct Pkcs1PublicEncryptingKey { /* private fields */ }

RSA PKCS1-v1.5 public key for encryption.

Implementations

impl Pkcs1PublicEncryptingKey

pub fn new( public_key: PublicEncryptingKey, ) -> Result<Pkcs1PublicEncryptingKey, Unspecified>

Constructs an Pkcs1PublicEncryptingKey from a PublicEncryptingKey.

Errors

• Unspecified: Any error that occurs while attempting to construct an RSA-OAEP public key.

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

Encrypts the contents in plaintext and writes the corresponding ciphertext to ciphertext. Returns the subslice of ciphertext containing the ciphertext output.

Max Plaintext Length

The provided length of plaintext must be at most Self::max_plaintext_size.

Sizing output

The length of output must be greater than or equal to Self::ciphertext_size.

Errors

• Unspecified for any error that occurs while encrypting plaintext.

pub fn key_size_bytes(&self) -> usize

Returns the RSA key size in bytes.

pub fn key_size_bits(&self) -> usize

Returns the RSA key size in bits.

pub fn max_plaintext_size(&self) -> usize

Returns the max plaintext that could be encrypted using this key.

pub fn ciphertext_size(&self) -> usize

Returns the max ciphertext size that will be output by Self::encrypt.
