token

token

Creates a token hash and verifies that a token matches a key and a cost.

How to use

Hash()

Creates a token hash using a strong one-way hashing algorithm (bcrypt).

Parameters

• key (string) - a key
• cost (integer) - which denotes the algorithmic cost that should be used

Example

import "github.com/martinusso/token"

token := token.Hash("123", 10)
fmt.Println(token)

The above example will optput something similar to:

Verify()

Verifies that a token hash matches a key and cost.

Parameters

• key (string) - a key
• cost (integer) - which denotes the algorithmic cost that should be used
• hash (string) - a token hash created by Hash method

Example

hash := "JDJhJDEwJDY1L3QwVFIyeFBMOWlNZWxxbWtzRU9HWUJ5MXZoajg2NExOU0FNTVZUQjEzR3dndjExTlYy"
fmt.Println(Verify("123", 10, hash))

The above example will output true.
