It usually is a permission issue. The chmod on the parent directories of your config file might be different between your two computers. (and I am not talking about just the immediate parent directory .ssh, but also all the parent directories) See “Git SSH authentication“, but also know that if any of the parent directories … Read more
Update Sept. 2022: 1Password supports generating and storing an SSH key for Git commit signature, recognized by GitHub. Update 2021: OpenSSH 8.2+ is available (packaged for instance in Git For Windows 2.33.1), and “it is now possible to sign arbitrary data with your SSH keys” (Andrew Ayer), including commits in Git. Andrew points to git/git … Read more
I had to add my public key to github. https://help.github.com/articles/generating-ssh-keys
Windows uses .cer extension for an X.509 certificate. These can be in “binary” (ASN.1 DER), or it can be encoded with Base-64 and have a header and footer applied (PEM); Windows will recognize either. To verify the integrity of a certificate, you have to check its signature using the issuer’s public key… which is, in … Read more
Ok @Adam and @Kimvais were right, Paramiko cannot parse .ppk files. So the way to go (thanks to @JimB too) is to convert .ppk file to OpenSSH private key format; this can be achieved using PuTTYgen as described here. Then it’s very simple getting connected with it: import paramiko ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(‘<hostname>’, username=”<username>”, … Read more
Java 7 is required for the EC functionality and Java 8 for the Base 64 encoder / decoder, no additional libraries – just plain Java. Note that this will actually display the public key as a named curve when printed out, something most other solutions won’t do. If you have an up-to-date runtime, this other … Read more
Unfortunately, the code in the answer you referenced isn’t really correct – it exports a private key PEM format, but with only the public key fields correctly set, this is not the same as exporting an RSA public key in standard format. I actually wrote the code in the other answer to that question, and … Read more
You can create an RSACryptoServiceProvider from a PEM file using the following class (GetRSAProviderFromPemFile method). Warning: Don’t just copy code from StackOverflow without verification! Especially not crypto code! This code has bugs (see comments). You may want to write and run tests before using this in production (if you really have no better option). I … Read more
If you have SSH installed, you should be able to run.. ssh-keygen Then go through the steps, you’ll have two files, id_rsa and id_rsa.pub (the first is your private key, the second is your public key – the one you copy to remote machines) Then, connect to the remote machine you want to login to, … Read more
I wanted to help explain what’s going on here. An RSA “Public Key” consists of two numbers: the modulus (e.g. a 2,048 bit number) the exponent (usually 65,537) Using your RSA public key as an example, the two numbers are: Modulus: 297,056,429,939,040,947,991,047,334,197,581,225,628,107,021,573,849,359,042,679,698,093,131,908,015,712,695,688,944,173,317,630,555,849,768,647,118,986,535,684,992,447,654,339,728,777,985,990,170,679,511,111,819,558,063,246,667,855,023,730,127,805,401,069,042,322,764,200,545,883,378,826,983,730,553,730,138,478,384,327,116,513,143,842,816,383,440,639,376,515,039,682,874,046,227,217,032,079,079,790,098,143,158,087,443,017,552,531,393,264,852,461,292,775,129,262,080,851,633,535,934,010,704,122,673,027,067,442,627,059,982,393,297,716,922,243,940,155,855,127,430,302,323,883,824,137,412,883,916,794,359,982,603,439,112,095,116,831,297,809,626,059,569,444,750,808,699,678,211,904,501,083,183,234,323,797,142,810,155,862,553,705,570,600,021,649,944,369,726,123,996,534,870,137,000,784,980,673,984,909,570,977,377,882,585,701 Exponent: 65,537 The question then becomes how do we want to store these … Read more
