basen

Package basen implements a radix encoding/decoding scheme, defined by a n-character alphabet.

base62

Base62 encoding encodes data using the character set 0-9A-Za-z. It is useful for generating strings that are safe to include in URLs, and allows easy copy and paste because a double-click will usually select the whole string.

Encode:

encoded := basen.Base62Encoding.EncodeToString([]byte("Hello"))
fmt.Println(encoded) // 5TP3P3v

Decode:

decoded, _ := basen.Base62Encoding.DecodeString("5TP3P3v")
fmt.Println(string(decoded)) // Hello

base58

Base58 encoding is base62 encoding modified to avoid letters which might look ambiguous when printed (i.e. 0, O, I, l). This reduces the risk of errors when a human is manually copying from some visual source.

Encode:

encoded := basen.Base58Encoding.EncodeToString([]byte("Hello"))
fmt.Println(encoded) // 9Ajdvzr

Decode:

decoded, _ := basen.Base58Encoding.DecodeString("9Ajdvzr")
fmt.Println(string(decoded)) // Hello
