Functions

func ParseASN1RSAPublicKey

func ParseASN1RSAPublicKey(derBytes []byte) (*rsa.PublicKey, error)

Parses a DER encoded RSA public key

func RSAEncrypt

func RSAEncrypt(pub *rsa.PublicKey, msg []byte) []byte

Encrypts a message with the given public key using RSA-OAEP and the sha1 hash function.

func SymmetricDecrypt

func SymmetricDecrypt(ciph cipher.Block, src []byte) []byte

Decrypts data from the reader using AES/CBC/PKCS7 with an IV prepended using AES/ECB/None. The src slice may not be used anymore.

func SymmetricEncrypt

func SymmetricEncrypt(ciph cipher.Block, src []byte) []byte

Performs an encryption using AES/CBC/PKCS7 with a random IV prepended using AES/ECB/None.
