crypto

crypto is a cryptographic toolkit for the Go programming language.

Getting Started

Install the package, along with executable binary helper (go 1.4 and greater is required):

$ go get -v github.com/goanywhere/crypto

Functions ¶

func Encrypt ¶

func Encrypt(src string) (secret string)

Encrypt creates a new password hash using a strong one-way bcrypt algorithm. Source secret is hashed with the given key (if set) before actual bcrypting.

func Random ¶

func Random(length int) string

Random creates a URL-safe random string which is based on the implementation with cryptographically secure pseudorandom number.

func Verify ¶

func Verify(src, secret string) bool

Verify checks that if the given hash matches the given source secret. Source secret is hashed with the given key (if set) before actual bcrypting.

Types ¶

type Signature ¶

type Signature struct {
	// contains filtered or unexported fields
}

func NewSignature ¶

func NewSignature(secret string) *Signature

NewSignature creates a signature with secret salt for encode/decode consequent values.

func (*Signature) Decode ¶

func (self *Signature) Decode(key, value string) (src []byte, err error)

Decode unpacks the source string to original values. Pattern:

signed value => base64 decode => nano|src(hex)|crc
verify crc
verify nano timestamp

func (*Signature) Encode ¶

func (self *Signature) Encode(key string, src []byte) (value string, err error)

Encode creates a checksum value for the given source using key, timestamp, crc. Pattern:

key|nano|src(hex) => hmac.sha1 => crc
nano|src(hex)|crc => base64 encode => signed value

NOTE struct value must be registered using gob.Register() first.
