![]() ![]() I still think a couple lines of code in GitBash is nothing to complain about when setting up SSH, compared to Tortoise anyway. What if I didn’t have SSH setup from the terminal before-hand? Of course, the path you see will have YOUR username in it, not Regan (MY username). If you’ve followed my guide, Getting Started with Git CLI for windows (Git Bash), then you already have an SSH Key, and can simply follow this gif: As a result, GitHub recommends that organizations check any SSH keys linked to their GitHub accounts-or any other service that uses a potentially vulnerable key-and rotate any keys that were generated using a vulnerable version of the library.NOTE: THIS IS NOT AN IMPORTANT STEP TO WORKING WITH GIT! This is for people who don’t like having to key in their username and password when using git. GitHub is notifying all of the account owners directly whose keys are affected by this, but Hanley said that it’s not possible to identify all of the potentially weak keys generated by clients that implemented a vulnerable version of the keypad library. In addition to revoking these keys, we have also implemented protections to prevent vulnerable versions of GitKraken from adding newly-generated weak keys by the older, vulnerable versions of the client in the future,” GitHub CSO Mike Hanley said. “Today as of 1700 UTC, we’ve revoked all keys generated by these vulnerable versions of the GitKraken client that were in use on, along with other potentially weak keys created by other clients that may have used the same vulnerable dependency. On Monday, GitHub revoked all of the weakly generated keys. "We’ve revoked all keys generated by these vulnerable versions of the GitKraken client that were in use on ."Įngineers at Axosoft, which makes GitKraken, discovered the weakness in keypair in late September and notified the developer, Julian Gruber, who wrote an advisory and implemented a fix on Oct. When it is not, the bytes are 0 through 9.” “The impact is that each byte in the RNG seed has a 97% chance of being 0 due to incorrect conversion. Generating identical values, repeatedly, usually indicates an issue with poor random number generation, or poor handling of CSPRNG output,” GitHub Security Lab said in a post on the issue. ![]() This would mean that the library is generating identical P, Q (and thus N) values which, in practical terms, is impossible with RSA-2048 keys. An issue was discovered where this library was generating identical RSA keys used in SSH. “keypair implements a lot of cryptographic primitives on its own or by borrowing from other libraries where possible, including node-forge. The vulnerable library was implemented in versions 7.6.x, 7.7.x, 8.0.0 of GitKraken, a tool that organizations use to access various services, including GitHub, GitLab, and others. The end result is that those keys could be guessed relatively easily and an attacker could then decrypt sensitive data or gain access to a victim’s account. In versions 1.0.3 and earlier, keypair contained a cryptographic flaw that caused it to generate extremely weak keys. The issue (CVE-2021-41117) lies in keypair, an open source library that generates RSA keys for SSH sessions in JavaScript. A serious cryptographic flaw in a library implemented in the GitKraken client used to generate RSA encryption keys for SSH sessions has led to a cascading series of events that caused GitHub to revoke all of the keys generated by vulnerable versions of GitKraken, as well as by other clients that used the vulnerable library. ![]()
