To the best of about accessible information, there is no accepted adjustment which will acquiesce a actuality or accumulation to breach PGP encryption by cryptographic or computational means. Indeed, in 1996, cryptographer Bruce Schneier characterized an aboriginal adaptation as actuality "the abutting you're acceptable to get to military-grade encryption."1 Aboriginal versions of PGP accept been begin to accept abstract vulnerabilities and so accepted versions are recommended. In accession to attention abstracts in alteration over a network, PGP encryption can additionally be acclimated to assure abstracts in abiding abstracts accumulator such as deejay files. These abiding accumulator options are additionally accepted as abstracts at rest, i.e. abstracts stored, not in transit.
The cryptographic aegis of PGP encryption depends on the acceptance that the algorithms acclimated are adamantine by absolute cryptanalysis with accepted accessories and techniques. For instance, in the aboriginal version, the RSA algorithm was acclimated to encrypt affair keys;
RSA's aegis depends aloft the one-way action attributes of
mathematical
integer factoring.2 Likewise, the symmetric key algorithm acclimated in PGP adaptation 2 was IDEA, which might, at some approaching time, be begin to accept a ahead buried cryptanalytic flaw. Specific instances of accepted PGP, or IDEA, insecurities—if they exist—are not about known. As accepted versions of PGP accept added added encryption algorithms, the amount of their cryptographic vulnerability varies with the algorithm used. In practice, anniversary of the algorithms in accepted use is not about accepted to accept cryptanalytic weaknesses.
New versions of PGP are appear periodically and vulnerabilities that developers are acquainted of are progressively fixed. Any bureau absent to apprehend PGP letters would apparently use easier bureau than accepted cryptanalysis, e.g. rubber-hose cryptanalysis or black-bag cryptanalysis i.e. installing some anatomy of trojan horse or keystroke logging
software
/hardware on the ambition computer to abduction encrypted keyrings and their passwords. The FBI has already acclimated this advance adjoin PGP34 in its investigations. However, any such vulnerabilities administer not aloof to PGP, but to all encryption software.
