func Decode ¶

func Decode(s string) ([]byte, error)

Decode decodes a standard base64-encoded string s into a byte slice.

This helper uses base64.StdEncoding. It allocates a destination buffer sized to the maximum decoded length, then returns the subslice actually written.

It returns a non-nil error if s contains invalid base64 data.

func Encode ¶

func Encode(src []byte) string

Encode encodes src using standard base64 encoding (RFC 4648) and returns the encoded string.

This helper uses base64.StdEncoding and allocates a new buffer sized to the encoded output.

func EncodedLen ¶ added in v2.457.0

func EncodedLen(size bytes.Size) int64

EncodedLen returns the length in bytes of the standard base64 encoding of size.
