gosecurity

Wrapper library that contains security-related stuff.

gocrypto

Encrypt and decrypt stuff using authenticated state-of-the-art crypto, provided by golang.org/x/crypto/nacl/secretbox.

usage

func GenerateKey() ([]byte, error)
func Encrypt(input []byte, key []byte) ([]byte, error)
func Decrypt(input []byte, key []byte) ([]byte, error)

format

<nonce(24b)><ciphertext>

gohash

Formats your password hashes in a standard (multihash-like) format so it keeps on working whenever you change algo. Defaults to Argon2id from golang.org/x/crypto/argon2.

usage

func GetHash(input string) (string, error)
func VerifyHash(hash string, input string) (bool, error)
func NeedsRehash(hash string) (bool, error)

format

$argon2$i:4:65536$IO+amcBFUXUETmI=$GpiSk2q1+y2DyfRVsg13BmIGE/oM0GLcM0SOs0s/H/s=

$<algo>$<parameters>$salt$key$
