crypto

func ComparePasswordHash ¶

func ComparePasswordHash(pwd, hash, salt string) (bool, error)

func Decrypt ¶

func Decrypt(key, text string) (string, error)

Decrypt text using the encryption key

func Encrypt ¶

func Encrypt(key, text string) (string, error)

Encrypt text using the encyption key

func MD5 ¶

func MD5(b []byte) string

MD5 is generally faster to compute than SHA-256

func NewEncryptionKey ¶

func NewEncryptionKey(size uint8) (string, error)

NewEncryptionKey will generate new key as base64 encoded string

should be of 16, 24 or 32 bytes in length

func NewPersistedED25519 ¶

func NewPersistedED25519() ([]byte, []byte, error)

NewPersistedED25519 public & private keys

func ParseEdPrivateKey ¶

func ParseEdPrivateKey(d []byte) (ed25519.PrivateKey, error)

func ParseEdPublicKey ¶

func ParseEdPublicKey(d []byte) (ed25519.PublicKey, error)

func PasswordHash ¶

func PasswordHash(pwd string) (hash, salt string, err error)

PasswordHash using Argon2id

func RandomBytes ¶

func RandomBytes(length uint8) ([]byte, error)

RandomBytes generates totally random bytes, each byte is generated by [0,255] range

func RandomBytesHex ¶

func RandomBytesHex(length uint8) (string, error)

func SHA256 ¶

func SHA256(b []byte) string

SHA256 Sum256 is generally preferred over md5.hash due to its superior security and resistance to collision attacks
