@isomorphic-pgp/parser

This isn't a full-featured parser - it parses just what is needed for the other libraries (generate, util, and sign-and-verify). Despite its name it is also a serializer.

To use one of the parsers, require the file directly. In order to prevent bundle bloat there is no main export that exports everything.

API

There's more, but these are the ones most likely to be useful.

• Message.parse|serialize
• PublicKey.parse|serialize|serializeForHash|fromJWK|toJWK
• SecretKey.parse|serialize|serializeForHash|fromJWK|toJWK
• UserId.parse|serialize|serializeForHash
• Signature.parse|serialize|serializeForHashTrailer
• UrlSafeBase64.parse|serialize
• Uint16.parse|serialize
• Uint32.parse|serialize
• emsa.encode(hashType, hash, length)
• convertPrivateToPublic(openpgpPrivateKey)
• certificationSignatureHashData(publicKeyPacket, userIdPacket, signaturePacket)
• payloadSignatureHashData(payload, signaturePacket)

Basic Usage

const Message = require('@isomorphic-pgp/parser/Message')

// Can be a public key, private key, or signature.
let message = `-----BEGIN PGP PUBLIC KEY BLOCK-----
