Date: Thu, 2 Mar 2023 01:03:20 +0100 From: Solar Designer <solar@...nwall.com> To: announce@...ts.openwall.com Cc: john-users@...ts.openwall.com Subject: John the Ripper in the cloud update 2023/02 Hi, As many of you recall, in 2020 we launched Openwall Password Recovery and Password Security Auditing Bundle in AWS Marketplace: https://www.openwall.com/john/cloud/ We provide a pre-generated Amazon Machine Image (AMI), which lets you start password recovery or a password security audit in minutes (if you've used Amazon Web Services before, or you need to sign up first). We've just updated the Bundle to use the latest John the Ripper jumbo as of 2023/02/22, which (compared to the version we had in the Bundle before) adds duplicate candidate password suppressor, new optimized default wordlist and rules, more rulesets, detailed status, new formats BestCryptVE4, Bitcoin-opencl, cardano, cryptosafe[-opencl], ENCDataVault-MD5, ENCDataVault-PBKDF2, NT-long, restic, RVARY, optimized descrypt and tezos-opencl, support for a wider variety of versions of previously supported formats (for 7z, Monero, Telegram, ZIP, and more), many reliability fixes and other changes. We've also enabled LM-opencl. Also updated are Amazon Linux 2 and NVIDIA GPU driver. Along with the above, we've enabled usage of the Bundle on many new AWS instance types: g4dn.* (which offer the smaller NVIDIA Tesla T4 GPUs, often at a better price/performance ratio than the V100's in our previously supported p3.* instances), p4d.24xlarge (which offers 8x NVIDIA A100 GPUs), and 6th generation Compute and Memory optimized Intel and AMD CPU instances (which offer higher maximum vCPU counts than 5th generation did, now up to 128 for Intel and 192 for AMD). Included on the Bundle homepage above are our latest benchmarks on p3.2xlarge (NVIDIA Tesla V100 GPU), c6i.32xlarge (2x Intel(R) Xeon(R) Platinum 8375C CPU, AVX-512), and c6a.48xlarge (2x AMD EPYC 7R13 Processor, AVX2). In terms of historical CPU speed milestones, both of these CPU instances are now firmly above 1 billion c/s at traditional Unix crypt(3) (aka descrypt) when cracking many salts, are at around 10 million c/s for md5crypt, and the AMD instance achieves 181k c/s at bcrypt cost 5. We've also updated the (spot) instance launch instructions to reflect changes in AWS EC2 Management Console, and made the Bundle itself hopefully more spot instance friendly: "Delete on termination" for the root volume is now disabled in the AMI (as the Console appears to no longer expose this option during instance launch), and the Bundle will automatically resume an unfinished John the Ripper job (which it does by issuing the "john --restore" command under "screen"). Any feedback and ideas are welcome on the john-users mailing list. Alexander
