const ( StdPadding rune = base64.StdPadding NoPadding rune = base64.NoPadding )
Variables ¶
var RawStdEncoding = StdEncoding.WithPadding(NoPadding)
RawStdEncoding is the standard unpadded base64 encoding defined in RFC 4648 section 3.2. This is the same as StdEncoding but omits padding characters.
var RawURLEncoding = URLEncoding.WithPadding(NoPadding)
RawURLEncoding is the unpadded alternate base64 encoding defined in RFC 4648. This is the same as URLEncoding but omits padding characters.
var StdEncoding = NewEncoding(encodeStd)
StdEncoding is the standard base64 encoding, as defined in RFC 4648.
var URLEncoding = NewEncoding(encodeURL)
URLEncoding is the alternate base64 encoding defined in RFC 4648. It is typically used in URLs and file names.

Types ¶
type Encoding ¶
An Encoding is a radix 64 encoding/decoding scheme, defined by a 64-character alphabet.
func NewEncoding ¶
NewEncoding returns a new padded Encoding defined by the given alphabet, which must be a 64-byte string that does not contain the padding character or CR / LF ('\r', '\n'). Unlike the standard library, the encoding alphabet cannot be abitrary, and it must follow one of the know standard encoding variants.
Required alphabet values:
- [0,26): characters 'A'..'Z'
- [26,52): characters 'a'..'z'
- [52,62): characters '0'..'9'
Flexible alphabet value options:
- RFC 4648, RFC 1421, RFC 2045, RFC 2152, RFC 4880: '+' and '/'
- RFC 4648 URI: '-' and '_'
- RFC 3501: '+' and ','
The resulting Encoding uses the default padding character ('='), which may be changed or disabled via WithPadding. The padding characters is urestricted, but it must be a character outside of the encoder alphabet.
