Functions

func Alpha

func Alpha(n int) string

Alpha generates a random string of n characters that only includes upper and lowercase letters (no symbols or digits)

func AlphaNumeric

func AlphaNumeric(n int) string

AlphaNumeric generates a random string of n characters that includes upper and lowercase letters and the digits 0-9

func CryptoRandInt

func CryptoRandInt() uint64

CryptoRandInt function generates a random 64-bit unsigned integer using cryptographic methods

func Decrypt

func Decrypt(cipherText string, key string) ([]byte, error)

Decrypt decrypts encrypted text with key (must be valid 32 chars aes key).

func Encrypt

func Encrypt(data []byte, key string) (string, error)

Encrypt encrypts data with key (must be valid 32 char aes key).

func Equal

func Equal(hash1 string, hash2 string) bool

Equal compares two hash strings for equality without leaking timing information

func GenerateRandomBytes

func GenerateRandomBytes(size int) []byte

GenerateRandomBytes returns random bytes

func GenerateRandomString

func GenerateRandomString(size int) string

GenerateRandomString returns a random string

func GenerateRandomStringHex

func GenerateRandomStringHex(size int) string

GenerateRandomStringHex returns a random hexadecimal string

func GenerateSHA256Hmac

func GenerateSHA256Hmac(secret string, data []byte) string

GenerateSHA256Hmac generates a SHA-256 HMAC by using the secret as the key and the data as the message

func HS256

func HS256(text string, secret string) string

HS256 creates a HMAC hash with sha256 digest algorithm.

func HS512

HS512 creates a HMAC hash with sha512 digest algorithm

func Hash

func Hash(value string) string

Hash returns a SHA-256 checksum of a string

func HashFromBytes

func HashFromBytes(value []byte) string

HashFromBytes returns a SHA-256 checksum of the input

func HashInput

func HashInput(input string) (string, error)

HashInput function takes an input and generates a bcrypt hash

func KeyID

func KeyID() string

KeyID returns a random ID that is of a fixed length with only alpha characters

func PrefixedSecret

func PrefixedSecret(prefix string) string

PrefixedSecret returns a prefixed random string of a fixed length with alpha-numeric characters

func S256Challenge

func S256Challenge(code string) string

S256Challenge creates [RFC 7636]: https://datatracker.ietf.org/doc/html/rfc7636#section-4.2

func SHA256

func SHA256(text string) string

SHA256 creates sha256 hash as defined in FIPS 180-4

func SHA512

func SHA512(text string) string

SHA512 creates sha512 hash as defined in FIPS 180-4

func Secret

func Secret() string

Secret returns a random string of a fixed length with alpha-numeric characters
