	Pretty Good Privacy - Wikipedia, the free encyclopedia
		OpenPGP is now an open standard used by PGP, GNU Privacy Guard (GnuPG), Hushmail, Veridis, Authora, and others.
		OpenPGP is still under active development and a follow-on to RFC 2440 is being actively finalized by the OpenPGP working group as of mid-2004.
		The OpenPGP standard specified mechanisms for negotiating agreement between the copies of PGP running at either end of a communications link as to which cipher algorithm is to be used with this or that message, as well as other feature additions after PGP 2.x.

	RFC 2440 (rfc2440) - OpenPGP Message Format
		OpenPGP's Radix-64 encoding is composed of two parts: a base64 encoding of the binary data, and a checksum.
		OpenPGP informs the user what kind of data is encoded in the ASCII armor through the use of the headers.
		OpenPGP CFB mode uses an initialization vector (IV) of all zeros, and prefixes the plaintext with ten octets of random data, such that octets 9 and 10 match octets 7 and 8.

		The OpenPGP Alliance is a growing group of companies and other organizations that are implementers of the OpenPGP Proposed Standard.

		OpenPGP's underlying native representation for encrypted messages, signature certificates, and keys is a stream of arbitrary octets.
		OpenPGP is designed for applications that use both encryption and signatures, but there are a number of problems that are solved by a signature-only implementation.

	RFC 3156 (rfc3156) - MIME Security with OpenPGP
		OpenPGP encrypted data Before OpenPGP encryption, the data is written in MIME canonical format (body and headers).
		OpenPGP encrypted data is denoted by the "multipart/encrypted" content type, described in [2], and MUST have a "protocol" parameter value of "application/pgp-encrypted".
		OpenPGP signed data OpenPGP signed messages are denoted by the "multipart/signed" content type, described in [2], with a "protocol" parameter which MUST have a value of "application/pgp-signature" (MUST be quoted).

		However, in the case of an OpenPGP message that is encrypted using a public key (which then has symmetric data), there's no need to do the quick check because the symmetric key comes from a public key encryption.
		OpenPGP encrypts the bulk of the message with a symmetric key and then encrypts that symmetric key with a public key.

	RFC2440 (Site not responding. Last check: 2007-10-07)
		OpenPGP provides data integrity services for messages and data files by using these core technologies: - digital signatures - encryption - compression - radix-64 conversion In addition, OpenPGP provides key management and certificate services, but many of these are beyond the scope of this document.
		OpenPGP packets are assembled into sequences in order to create messages and to transfer keys.
		Some OpenPGP applications use so-called "detached signatures." For example, a program bundle may contain a file, and with it a second file that is a detached signature of the first file.

	NewsForge \| Securing Thunderbird email with OpenPGP
		Email is commonly used in business today, yet only a small percentage of users take the time to guarantee their email is sent in a secure and confidential manner.
		OpenPGP is a patent-free encryption scheme based on the same security architecture as the commercial version of PGP, which has been available since the early 90's.
		Since being able to correlate signed messages with public OpenPGP keys is part of receiving secure messages, Enigmail also offers the possibility to import all the public keys of your contacts.

	OpenPGP.org - About OpenPGP
		OpenPGP is a non-proprietary protocol for encrypting email using public key cryptography.
		Beginning in 1997, the OpenPGP Working Group was formed in the Internet Engineering Task Force (IETF) to define this standard that had formerly been a proprietary product since 1991.
		The OpenPGP Alliance brings companies together to pursue a common goal of promoting the same standard for email encryption and to apply the PKI that has emerged from the OpenPGP community to other non-email applications.

		OpenPGP keys also contain public parameters of a public key algorithm, and signatures from several other parties.
		Certificate verification is possible by loading the trusted authorities into the credentials structure by using gnutls_certificate_set_x509_trust_file or gnutls_certificate_set_openpgp_keyring_file for openpgp keys.
		Note however that the peer's certificate is not automatically verified, you should call gnutls_certificate_verify_peers, after a successful handshake, to verify the signatures of the certificate.

	S/MIME And OpenPGP Vie For Security Title
		You'll have to choose between the two: S/MIME and OpenPGP can't work together, so if you want to send a digitally signed and encrypted message to your business partner, both of you have to be using the same secure mail protocol.
		OpenPGP and its earlier iterations, meanwhile, haven't garnered equal high-profile acceptance among vendors.
		Nowadays, OpenPGP and S/MIME are no longer so different technology-wise, which is why some IETF members question the need for parallel protocol efforts for secure e-mail.

	[Announce] Attack against OpenPGP encryption
		To be specific, unless you have your OpenPGP program set up as part of an automated system to accept encrypted messages, decrypt them, and then provide a response to the submitter, then this does not affect you at all.
		This is why it is completely ineffective against human beings, who will presumably wonder why a stranger wants them to decrypt thousands and thousands of messages that won't decrypt, and then tell them what errors were seen.
		These patches disable a portion of the OpenPGP protocol that the attack is exploiting.

		But perhaps I start by explaining what OpenPGP is. Or if you prefer, you may skip the lecture and grap my key right away.
		OpenPGP is a way to use public-key cryptography to sign and encrypt email.
		If you are having touble with my email because of such programs, My first advise will be to look at some other mail programs, since there might be other poorly written parts of whatever you are using now.

	OpenPGP Alliance omits PGP Security \| The Register
		The OpenPGP Alliance, which was founded by PGP creator Phil Zimmermann, doesn't include Network Associates, whose PGP Security division owns the source code and trademark for the popular PGP encryption package first developed by Zimmermann in 1991.
		OpenPGP, a non-proprietary protocol for encrypting email using public key cryptography based on the PGP program, was submitted to the Internet Engineering Task Force (IETF) in 1997.
		Interoperability between different encryption packages is an important issue and so formation of the OpenPGP Alliance is welcome but the lack of involvement of Network Associates could be a stumbling block in the future.
