Struct Pkcs1PrivateDecryptingKey

pub struct Pkcs1PrivateDecryptingKey { /* private fields */ }

RSA PKCS1-v1.5 private key for decryption.

Implementations

impl Pkcs1PrivateDecryptingKey

pub fn new(private_key: PrivateDecryptingKey) -> Result<Self, Unspecified>

Constructs an Pkcs1PrivateDecryptingKey from a PrivateDecryptingKey.

Errors

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

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

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

Max Ciphertext Length

The provided length of ciphertext must be Self::key_size_bytes.

Sizing output

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

Errors

• Unspecified for any error that occurs while decrypting ciphertext.

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 min_output_size(&self) -> usize

Returns the minimum plaintext buffer size required for Self::decrypt.
