WebTo understand where the security problem discovered by De Feo, Poettering and Sorniotti hides, we need to have a deeper look at the ElGamal public-key encryption scheme which is one of the required public-key algorithms specified in RFC4880 (the technical document that describes how OpenPGP should operate). Web9 de jul. de 2024 · Each library in the OpenPGP ecosystem seems to have implemented a slightly different "flavour" of ElGamal encryption. While --taken in isolation-- each implementation may be secure, we reveal that in the interoperable world of OpenPGP, unforeseen cross-configuration attacks become possible.
