DH Parameter
Hi! Is there any possibility to let dovecot serve >1024 Bit DH Parameters at SSL/TLS-connections? Is it possible to replace /var/lib/dovecot/ssl-parameters.ssl with DH-parameter generated by openssl? If not: Are there any plans to implement that? Thank you!

DH Group Exchange Fallback
Hi, I'm interested in requiring a minimum of 3072-bit DH moduli when using the "diffie-hellman-group-exchange-sha256" kex, so I edited my /etc/ssh/moduli file such that only 3071+ moduli are left. However, when clients ask for a max of 2048-bit moduli, they actually get one (!). I poked around and found that a fallback mechanism exists (dh.c:185), which returns back the

Modulus operator??
I'm trying to do a modulus operator in R-1.2.2 on Windows -- specific version: R : Copyright 2001, The R Development Core Team Version 1.2.2 Patched (2001-03-22) Here's what the R language manual says: "R contains a number of operators. They are listed in the table below. [snip] % Modulus, binary" Here's what happens on the R console: > records <- 100000 >

3des cipher and DH group size
Hello everybody, An issue was reported in RH bugzilla [1] about the size of the used DH group when combined with the 3des-cbc cipher. OpenSSH uses the actual key length for the size estimation. This is probably fine as far as the cipher has the same number of bits of security as the key length. But this is not true for 3TDEA where the key size is 168 resp 192 but it's security is only 112.

diffie-hellman-group-exchange-sha256 group size concerns and request
Hello all, I have recently had cause to dig a little into the specifics of how diffie-hellman-group-exchange-sha256 group sizes work. The belief in the wild, perpetuated by multiple sources of logjam mediation papers and also Andras Stribnik's very influential piece "Secure Secure Shell", is that server operators can force the use of a minimum group size by removing moduli

How to calculate modulus of complex number
suppose I have following complex number : a = -0.0475983+0.5364486i This number I got as an eigen value of a matrix. Now I would like to calculate the Modulus of this complex number. Is there any function for doing that?

Java, JCE and OpenSSH
Hello, all. Firstly, sorry for the cross-posting... Has anyone out there tried to use JCE (1.2.1, with JDK1.3.1) to create a Diffie Hellman key using the group1 prime modulus and base generator, and then pass on the public key to an OpenSSH (v3.1) server as a part of the diffie-hellman-group1-sha1 key exchange? For some reason, the ssh server rejects the key saying it is invalid ... I have

Integer bit size and the modulus operator
I am a statistician and I come up to an interesting problem in cryptography. I would like to use R since there are some statistical procedures that I need to use. However, I run into a problem when using the modulus operator %%. I am using R 2.2.1 and when I calculate modulus for large numbers (that I need with my problem) R gives me warnings. For instance if one does: a=1:40; 8^a %% 41 one

Modulus Problem
R users, I am having a problem with the modulus operator for large numbers as follows, a <- 2 n <- 561 ## n is the first Carmichael number, so by Fermat's Little Theorem the below should equal zero. (a^(n-1) - 1) %% n [1] 2.193172e+152 ## Seems that R and Fermat disagree ## Also, 1000000000000000000 %% 11 [1] -32 This seems like a bug. Should I be avoiding integer math for large
