Functions

func Generate

func Generate(password []byte, s ...[]byte) ([]byte, error)

Generate generates a new hashed password

Example

hash, err := Generate([]byte("password"), []byte("salt            "))
if err != nil {
	panic(err)
}
fmt.Printf("Hash: %x\n", hash)

Output:

Hash: 73616c7420202020202020202020202056a3984c5b69cbc7819ff6097dc4fb65f154d5509d0c021f6bc8e7c135253eb3

func Verify

func Verify(password, hash []byte) (bool, error)

Verify verifies a password against a hash

Example

hash, _ := hex.DecodeString("73616c7420202020202020202020202056a3984c5b69cbc7819ff6097dc4fb65f154d5509d0c021f6bc8e7c135253eb3")
ok, err := Verify([]byte("password"), hash)
if err != nil {
	panic(err)
}
fmt.Printf("Password verification: %t\n", ok)

Output:

Password verification: true
