keygen

Generates cryptographically random keys that can be used as session ids, api keys or authentication tokens etc. Generated keys support:

• multiple charsets (Base58, Base62, RFC6265 cookie compatible or custom unicode compatible charset)
• minimum entropy, or
• key length (number of characters)

You can also override the following parameters:

• character set (default: [a-z][A-Z][0-9])
• minimum entropy (default: 128 bits)
• key length (default: 0)

Installation

go get https://github.com/justasable/keygen

Example Usage

Using Default Values

k, err := keygen.New(nil)
key, err := k.Key()

Using Config

k, err := keygen.New(&keygen.Config{
    Charset: keygen.CharsetRFC6265,
    MinEntropy: 256,
})
key, err := k.Key()

Setting Custom Charset and Key Length

k, err := keygen.New(&keygen.Config{
    Charset: "日本語",
    KeyLength: 10,
})
key, err := k.Key()
