This problem is in v7.5 and v7.6. See dh.c:436. > OpenSSH 6.6 was first released on October 6, 2014. I brought up v6.6 to give an example that older clients wouldn't be

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!

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

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.

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?

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

Is there a modulus operator in R? Anna

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

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

Hi, You will be aware of https://weakdh.org/ by now, I presume; the take-home seems to be that 1024-bit DH primes might well be too weak. I'm wondering what (if anything!) you propose to do about this issue, and what Debian might do for our users? openssh already prefers ECDH, which must reduce the impact somewhat, although the main Windows client (PuTTY) doesn't support ECDH yet. But

Dear R friends, I was wondering if there were factorial and modulus functions out there that I've somehow overlooked? -P. -- Peter L.
