Bug#494194: gnupg: Choice of algorithms for --symmetric is obscure

2008-08-08 Thread Werner Koch
Hi! You are mixing up two things: 1. The key derivation function, commonly abbreviated as KDF but in OpenPGP as S2K (String to Key). 2. The encrytion algorithm. The first is use to derive a key from a passphrase and the second to do the actual encryption. The goal of the key derivation is t

Package: gnupg Version: 1.4.9-2 Severity: normal Hi! The choice of algorithms used for conventional encryption of messages (--symmetric) is quite obscure. The user must provide a passphrase which is hashed, the result of which is used as an encryption key. Now, the hash is selected by "s2k-digest
