package armor

import "golang.org/x/crypto/openpgp/armor"

Package armor implements OpenPGP ASCII Armor, see RFC 4880. OpenPGP Armor is very similar to PEM except that it has an additional CRC checksum.

Package Files ¶

armor.go encode.go

Variables ¶

var ArmorCorrupt error = errors.StructuralError("armor invalid")

func Encode ¶

func Encode(out io.Writer, blockType string, headers map[string]string) (w io.WriteCloser, err error)

Encode returns a WriteCloser which will encode the data written to it in OpenPGP armor.

type Block ¶

type Block struct {
    Type   string            // The type, taken from the preamble (i.e. "PGP SIGNATURE").
    Header map[string]string // Optional headers.
    Body   io.Reader         // A Reader from which the contents can be read
    // contains filtered or unexported fields
}

A Block represents an OpenPGP armored structure.

The encoded form is:

-----BEGIN Type-----
Headers

base64-encoded Bytes
'=' base64 encoded checksum
-----END Type-----

where Headers is a possibly empty sequence of Key: Value lines.

Since the armored data can be very large, this package presents a streaming interface.

func Decode ¶

func Decode(in io.Reader) (p *Block, err error)

Decode reads a PGP armored block from the given Reader. It will ignore leading garbage. If it doesn't find a block, it will return nil, io.EOF. The given Reader is not usable after calling this function: an arbitrary amount of data may have been read past the end of the block.
