base64

Standard Encoding/Decoding

import (
    "encoding/base64"
    "fmt"
)

func main() {
    data := []byte("test data")

    b64Enc := base64.StdEncoding.EncodeToString([]byte(data))
    fmt.Println("B64 Encoded:", b64Enc)
    b64Dec, err := base64.StdEncoding.DecodeString(b64Enc)
    if err != nil {
        fmt.Println("Failed to b64 decode")
    }
    fmt.Println("B64 Decoded:", string(b64Dec))
}

URL Safe Encoding/Decoding

import (
    "encoding/base64"
    "fmt"
)

func main() {
    data := []byte("test data")

    b64UEnc := base64.URLEncoding.EncodeToString([]byte(data))
    fmt.Println("B64 URLEncoded:", b64UEnc)
    b64UDec, err := base64.URLEncoding.DecodeString(b64UEnc)
    if err != nil {
        fmt.Println("Failed to b64 url decode")
    }
    fmt.Println("B64 URLDecoded:", string(b64UDec)
}

base32

import (
    "encoding/base32"
    "fmt"
)

func main() {
    data := []byte("test data")

    b32Enc := base32.StdEncoding.EncodeToString([]byte(data))
    fmt.Println("B32 Encoded:", b32Enc)
    b32Dec, err := base32.StdEncoding.DecodeString(b32Enc)
    if err != nil {
        fmt.Println("Failed to b32 decode")
    }
    fmt.Println("B32 Decoded:", string(b32Dec))
}

base58

Need to install base58 package:

$ go get github.com/mr-tron/base58

Code:

import (
    "fmt"

    "github.com/mr-tron/base58"
)

func main() {
    data := []byte("test data")

    b58Enc := base58.Encode(data)
    fmt.Println("B58 Encoded:", b58Enc)
    b58Dec, err := base58.Decode(b58Enc)
    if err != nil {
        fmt.Println("Failed to b58 decode")
    }
    fmt.Println("B58 Decoded:", string(b58Dec))
}
