( CorruptInputError) Error() string CorruptInputError : error
An Encoding is a radix 32 encoding/decoding scheme, defined by a 32-character alphabet. The most common is the "base32" encoding introduced for SASL GSSAPI and standardized in RFC 4648. The alternate "base32hex" encoding is used in DNSSEC. AppendDecode appends the base32 decoded src to dst and returns the extended buffer. If the input is malformed, it returns the partially decoded src and an error. AppendEncode appends the base32 encoded src to dst and returns the extended buffer. Decode decodes src using the encoding enc. It writes at most [Encoding.DecodedLen](len(src)) bytes to dst and returns the number of bytes written. If src contains invalid base32 data, it will return the number of bytes successfully written and [CorruptInputError]. Newline characters (\r and \n) are ignored. DecodeString returns the bytes represented by the base32 string s. DecodedLen returns the maximum length in bytes of the decoded data corresponding to n bytes of base32-encoded data. Encode encodes src using the encoding enc, writing [Encoding.EncodedLen](len(src)) bytes to dst. The encoding pads the output to a multiple of 8 bytes, so Encode is not appropriate for use on individual blocks of a large data stream. Use [NewEncoder] instead. EncodeToString returns the base32 encoding of src. EncodedLen returns the length in bytes of the base32 encoding of an input buffer of length n. WithPadding creates a new encoding identical to enc except with a specified padding character, or NoPadding to disable padding. The padding character must not be '\r' or '\n', must not be contained in the encoding's alphabet, must not be negative, and must be a rune equal or below '\xff'. Padding characters above '\x7f' are encoded as their exact byte value rather than using the UTF-8 representation of the codepoint. func NewEncoding(encoder string) *Encoding func Encoding.WithPadding(padding rune) *Encoding func NewDecoder(enc *Encoding, r io.Reader) io.Reader func NewEncoder(enc *Encoding, w io.Writer) io.WriteCloser var HexEncoding *Encoding var StdEncoding *Encoding
Package-Level Functions (total 3)
NewDecoder constructs a new base32 stream decoder.
NewEncoder returns a new base32 stream encoder. Data written to the returned writer will be encoded using enc and then written to w. Base32 encodings operate in 5-byte blocks; when finished writing, the caller must Close the returned encoder to flush any partially written blocks.
NewEncoding returns a new padded Encoding defined by the given alphabet, which must be a 32-byte string that contains unique byte values and does not contain the padding character or CR / LF ('\r', '\n'). The alphabet is treated as a sequence of byte values without any special treatment for multi-byte UTF-8. The resulting Encoding uses the default padding character ('='), which may be changed or disabled via [Encoding.WithPadding].

HexEncoding is the “Extended Hex Alphabet” defined in RFC 4648. It is typically used in DNS.
StdEncoding is the standard base32 encoding, as defined in RFC 4648.
