Go PGP

Layer on top of golang.org/x/crypto/openpgp to handle a few PGP use cases.
Fork of https://github.com/jchavannes/go-pgp.

Additions

• Support for multi key encryption
• Expanded Key Pair with rsa value

Examples

Encryption

pgp/encrypt_test.go

Encrypt

// Create public key entity
pubEntity, _ := pgp.GetEntity(publicKeyPacket, nil)

// Encrypt message
encrypted, _ := pgp.Encrypt(pubEntity, []byte(TestMessage))

Decrypt

// Create private key entity
privEntity, _ := pgp.GetEntity([]byte(TestPublicKey), []byte(TestPrivateKey))

// Decrypt message
decrypted, _ := pgp.Decrypt(privEntity, encrypted)

Signing

pgp/sign_test.go

Sign

// Create private key entity
entity, _ := pgp.GetEntity([]byte(TestPublicKey), []byte(TestPrivateKey))

// Sign message
signature, _ := pgp.Sign(entity, []byte(TestMessage))

Verify

// Create public key packet
entity, _ := pgp.GetEntity([]byte(TestPublicKey), []byte(TestPrivateKey))

// Verify signature
err = pgp.Verify(entity, []byte(TestMessage), signature)
if err == nil {
    fmt.Println("Signature verified.")
}
