    Functions

    func GetChecksumHash

    func GetChecksumHash(b, key []byte, usage uint32, etype etype.EType) ([]byte, error)

      GetChecksumHash returns a keyed checksum hash of the bytes provided.

      func GetHash

      func GetHash(pt, key []byte, usage []byte, etype etype.EType) ([]byte, error)

        GetHash generates the keyed hash value according to the etype's hash function.

        func GetIntegrityHash

        func GetIntegrityHash(b, key []byte, usage uint32, etype etype.EType) ([]byte, error)

          GetIntegrityHash returns a keyed integrity hash of the bytes provided.

          func GetUsageKc

          func GetUsageKc(un uint32) []byte

            GetUsageKc returns the checksum key usage value for the usage number un.

            See RFC 3961 5.3 key-derivation function definition.

            func GetUsageKe

            func GetUsageKe(un uint32) []byte

              GetUsageKe returns the encryption key usage value for the usage number un

              See RFC 3961 5.3 key-derivation function definition.

              func GetUsageKi

              func GetUsageKi(un uint32) []byte

                GetUsageKi returns the integrity key usage value for the usage number un

                See RFC 3961 5.3 key-derivation function definition.

                func IterationsToS2Kparams

                func IterationsToS2Kparams(i uint32) string

                  IterationsToS2Kparams converts the number of iterations as an integer to a string representation.

                  func PKCS7Pad

                  func PKCS7Pad(b []byte, m int) ([]byte, error)

                    PKCS7Pad pads bytes according to RFC 2315 to nearest multiple of message size m.

                    func PKCS7Unpad

                    func PKCS7Unpad(b []byte, m int) ([]byte, error)

                      PKCS7Unpad removes RFC 2315 padding from byes where message size is m.

                      func VerifyChecksum

                      func VerifyChecksum(key, chksum, msg []byte, usage uint32, etype etype.EType) bool

                        VerifyChecksum compares the checksum of the msg bytes is the same as the checksum provided.

                        func ZeroPad

                        func ZeroPad(b []byte, m int) ([]byte, error)

                          ZeroPad pads bytes with zeros to nearest multiple of message size m.
