similar to: using OpenSSL blowfish algorithm

Hello all, Hoping someone can help me out here. I''ve burned almost a week trying to figure out how to decrypt an image file that has been encrypted using Blowfish CBC. I found some code on the net and have modified as follows: require ''openssl'' require ''digest/sha1'' ivArr = [0x0D, 0x0E, 0x0A, 0x0D, 0x0F, 0x0A, 0x0C, 0x0E ]

Hello everybody, Thank you Fufu Fang for your quick reply: With tinc version 1.0.35 and the bellow options at 100% CPu load i get about 10 MB/s... PMTU = 1400 PMTUDiscovery = yes #Cipher = none Cipher = chacha20-poly1305 Digest = blake2b512 Tried Cipher = none as well and also got 10MB/s with 100% CPU on one thread the other three available threads are idle. With inc_1.1~pre17-1.1_amd64.deb

Hello everybody, First a big thanks for tinc-vpn I am still using it next to wireguard and openvpn. I am having a setup where the tinc debian appliance is at 100% cpu load doing about 7.5MB/s. Compression = 9 PMTU = 1400 PMTUDiscovery = yes Cipher = aes-128-cbc How can I pick a cipher that is the fasted for my CPU and don't create a CPU bottleneck at 100%. Kind regards, Jelle de Jong

Hi, I'm doing some perf profiling, and I can see that BF_encrypt & BF_decrypt of libcrypto.so.1.0.0 (used in tincd) are consuming CPU time. I'm using Tinc 1.0.23 and Cipher = aes-128-cbc BF_encrypt & BF_decrypt seems related to Blowfish (https://www.openssl.org/docs/crypto/blowfish.html). Is it normal that BF functions are used even if AES is used ? I do not know anything about

When testing chacha20-poly1305, I noticed that aes-gcm is significantly faster than aes-ctr or aes-cbs with umac. Even on systems w/o aes-ni or other recent instruction set additions. And there seems to be consensus in the crypto community that AEAD ciphers are the way forward. As such, it promoting the AEAD ciphers to the head of the preference list looks like a good idea. That would mean

HI Im creating a rails app using blowfish encryption and decryption, in my app i have included a gem crypt for doing a encryption and im trying to decrypt the result using blowfish.js is that possible to do that encryption via ruby gem and decryption via blowfish.js, i download the blowfish js from the url: http://dren.ch/js/blowfish.js Is it possible to implement encryption via ruby

Hi, Connecting from RHL7 with OpenSSH 2.3.0p1 or 2.5.0p1 to OpenSSH 2.3.0p1 on AIX 4.3.1. Protocol 2 doesn't work if you specify 'Ciphers rijndael128-cbc' or Ciphers 'aes128-cbc'. sshd -d -d -d on the server shows _nothing_ about these connections. I'm not sure if rijndael has been left out from sshd somehow, but shouldn't the error message be a little more

Hello developers, some informations before I come to the problem: At work we're using Open-SSH 3.4p1 under Solaris 8. I compiled the Open-SSH by myself with gcc-3.1. In the gcc is the bounds checking patch included (http://web.inter.nl.net/hcc/Haj.Ten.Brugge/bounds-checking-gcc-3.1-1.01.patch.bz2). With this patch I compiled: - prngd 0.9.25 - zlib 1.1.4 - Open-SSL 0.9.6d Everything

Greetings, I am trying to cross compile OpenSSH 4.7 for ppc with QNX Neutrino as my OS. I have a workstation with QNX on it (x86) and I have linked the utils used by autoconf to their ppc versions. I have been able to successfully build sshd/ssh. I copy the binaries built on the x86 to the ppc, and sshd works great. I can ssh from any machine to it, but when I try to ssh from the ppc machine to

Does anyone knows which one is the strongest and which is the fastest encryption algorithms used in OpenSSH 3.7.1p2 from the list below aes128-cbc, 3des-cbc, blowfish-cbc, cast128-cbc, arcfour, aes192-cbc, aes256-cbc, rijndael-cbc at lysator.liu.se, aes128-ctr, aes192-ctr, aes256-ctr Strong Encryption OpenSSH supports 3DES, Blowfish, AES and arcfour as encryption algorithms. These are patent

Hello, I understand that I can use the openssl ciphers and digests available on my systems, i.e. those in the list generated by "openssl list-cipher-commands" and "openssl list-message-digest-algorithms". I want to create a admin vpn network between my servers and my workplace. Network throughput is not a big issue, I am using ssh and the cli, however I would also do

Hi Team, I have a question regarding open ssh issue. We have a SFTP automate process to upload file at customer server using ssh key based authentication. But some simultaneously process going in hung state. I have enable verbose mode but I am not able to understand that log. Can you please let us know by below log why we are facing this issue? While process going in hung state:-

Hi folks, I'm playing with this version of OpenSSL: openssl-SNAP-20100804 On x86 using clang I can build it and run all tests successfully. On x86-64 using clang r110287 I get the error message below during "make test". Not sure if anyone has time to look into this but I'm probably not the right person to start debugging it... Thanks, John Regehr

Hi all. Solaris 10's default libcrypto does not have support for AES 192 and 256 bit functions. The attached patch, against -current, and based partially on an earlier one by djm, will use OpenSSH's builtin rijndael code for all AES crypto functions and thus will allow it to build and function on Solaris 10 without the extra crypto packages (SUNWcry, SUNWcryr) or a locally built OpenSSL.

When is the x.509 patch going to become part of the main distribution of OpenSSH, and if not, why? Looks like other projects i.e. OpenSC might be using it now as well. Secondly, thought I'd try it again, new patch (Validator), same error...
