Struct aws_nitro_enclaves_cose::crypto::Openssl

pub struct Openssl;

Type that implements various cryptographic traits using the OpenSSL library

Trait Implementations

impl Decryption for Openssl

fn decrypt_aead( algo: EncryptionAlgorithm, key: &[u8], iv: Option<&[u8]>, aad: &[u8], ciphertext: &[u8], tag: &[u8] ) -> Result<Vec<u8>, CoseError>

Like decrypt, but for AEAD ciphers such as AES GCM.

Additional Authenticated Data can be provided in the aad field, and the authentication tag should be provided in the tag field.

impl Encryption for Openssl

fn encrypt_aead( algo: EncryptionAlgorithm, key: &[u8], iv: Option<&[u8]>, aad: &[u8], data: &[u8], tag: &mut [u8] ) -> Result<Vec<u8>, CoseError>

Like encrypt, but for AEAD ciphers such as AES GCM.

Additional Authenticated Data can be provided in the aad field, and the authentication tag will be copied into the tag field.

The size of the tag buffer indicates the required size of the tag. While some ciphers support a range of tag sizes, it is recommended to pick the maximum size. For AES GCM, this is 16 bytes, for example.

impl Entropy for Openssl

fn rand_bytes(buff: &mut [u8]) -> Result<(), CoseError>

Fill the provided buff with cryptographic random values.

impl Hash for Openssl

fn hash(digest: MessageDigest, data: &[u8]) -> Result<Vec<u8>, CoseError>

Computes the hash of the data with provided hash function
