8192bit RSA keys
Hey folks, Two years ago, there was a thread on this list, in which RSA key sizes >2048 were discussed [0]. In these two years, the crypto-world has been shaken up a bit, and computers got yet a bit more powerful. 0. http://lists.gnupg.org/pipermail/gnupg-users/2007-June/031285.html I am trying to decide whether I want to create myself a new RSA key and am looking at key lengths of 2k, 4k, and 8k. In theory, I'd like to use the 8k variant, simply because I postulate that my machines can handle it (I don't use GPG on a PDA/SmartPhone (yet)), but I don't know if this makes sense in practice. I understand RSA and I cannot imagine compatibility problems with other implementations, but I'd still like to reopen the issue and ask this list what they think about >2048bit keys, and 8192bit in particular.

It depends on what you're protecting against. For most common cases, a 8192-bit RSA key is likely so vastly stronger than the rest of your environment that a smart attacker wouldn't bother to attack it. They'd just go after what they want via other attacks against you and/ or your environment. Mind you, the same thing is true for a 2048-bit RSA key as well. (I'd wager that for many people, the same thing is also true for a 512-bit RSA key). If you can get the same end result with a smaller key, you need to ask yourself what the big key actually buys you. If you're looking for a more immediate reason, though, note that if you make a RSA key larger than 2048 bits you can't use it with the spiffy new OpenPGP smartcard.

Opinions on RIPEMD vs SHA?
I'm considering making my default hash RIPEMD160: does anyone have any opinions on how this compares to SHA-2 algorithms in terms of both security and availability? I like the idea that RIPEMD was developed in an academic community instead of the NSA, but if there are genuine benefits to using SHA, I have no problem looking past this bit of romanticism.

I'm especially curious if RIPEMD160 is commonly available in popular PGP clients. RIPEMD160 is nearly universally supported in popular PGP clients. It's been around for a long time. That said, you can't compare it to SHA-2. I believe your academia/NSA comparison is invalid (it's really just romanticism), but I'm not even going to bother to restart the common algorithm/peer review/more attacks/etc discussion that we've had a zillion times on this list, and instead jump right to the easy reason: RIPEMD160 is 160 bits long. SHA-2 is (at minimum) 224 bits long, and can go up to 512 bits long. 224 > 160. 512 is very > 160. Unless you think SHA-2 is actually weaker than RIPEMD160 somehow, why would you not use it?

RIPEMD160 is a pure European algorithm and by design not different than SHA-1; like most hash algorithms it is based on the same principles as MD4 is. There is no reason to believe that RIPEMD-160 is stronger than the SHA-1. If you want to do business with European governments you need to support RIPEMD-160 - well at least until last year.

Re: Opinions on RIPEMD vs SHA?
I'm considering making my default hash RIPEMD160: does anyone have any opinions on how this compares to SHA-2 algorithms in terms of both security and availability? The new SHAs have the benefit of about a dozen years of cryptanalytic research behind them. RIPEMD160 is very similar to SHA-1, and the recent attacks against SHA-1 are likely applicable to RIPEMD160. Those same attacks do not apply against the newer SHAs. I have no problem looking past this bit of romanticism. "Romanticism" is exactly the right word to use. I'm especially curious if RIPEMD160 is commonly available in popular PGP clients. Yes. It's been in PGP since 6.5.8, and in GnuPG since 1.0. (Probably since long before 1.0, but since 1.0 was the first official release, that's where I trace things back to.) ___ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
