Functions

func DecryptData

func DecryptData(key, data []byte, e etype.EType) ([]byte, error)

DecryptData decrypts the data provided using the methods specific to the etype provided as defined in RFC 3962.

func DecryptMessage

func DecryptMessage(key, ciphertext []byte, usage uint32, e etype.EType) ([]byte, error)

DecryptMessage decrypts the message provided using the methods specific to the etype provided as defined in RFC 3962. The integrity of the message is also verified.

func EncryptData

func EncryptData(key, data []byte, e etype.EType) ([]byte, []byte, error)

EncryptData encrypts the data provided using methods specific to the etype provided as defined in RFC 3962.

func EncryptMessage

func EncryptMessage(key, message []byte, usage uint32, e etype.EType) ([]byte, []byte, error)

EncryptMessage encrypts the message provided using the methods specific to the etype provided as defined in RFC 3962. The encrypted data is concatenated with its integrity hash to create an encrypted message.

func S2KparamsToItertions

func S2KparamsToItertions(s2kparams string) (int64, error)

S2KparamsToItertions converts the string representation of iterations to an integer

func StringToKey

func StringToKey(secret, salt, s2kparams string, e etype.EType) ([]byte, error)

StringToKey returns a key derived from the string provided according to the definition in RFC 3961.

func StringToKeyIter

func StringToKeyIter(secret, salt string, iterations int64, e etype.EType) ([]byte, error)

StringToKeyIter returns a key derived from the string provided according to the definition in RFC 3961.

func StringToPBKDF2

func StringToPBKDF2(secret, salt string, iterations int64, e etype.EType) []byte

StringToPBKDF2 generates an encryption key from a pass phrase and salt string using the PBKDF2 function from PKCS #5 v2.0
