You can’t just change the delimiters from —- BEGIN SSH2 PUBLIC KEY —- to —–BEGIN RSA PUBLIC KEY—– and expect that it will be sufficient to convert from one format to another (which is what you’ve done in your example). This article has a good explanation about both formats. What you get in an RSA … Read more
See https://polarssl.org/kb/cryptography/asn1-key-structures-in-der-and-pem (search the page for “BEGIN RSA PRIVATE KEY”) (archive link for posterity, just in case). BEGIN RSA PRIVATE KEY is PKCS#1 and is just an RSA key. It is essentially just the key object from PKCS#8, but without the version or algorithm identifier in front. BEGIN PRIVATE KEY is PKCS#8 and indicates that … Read more
When encrypting, you use their public key to write a message and they use their private key to read it. When signing, you use your private key to write message’s signature, and they use your public key to check if it’s really yours. I want to use my private key to generate messages so only … Read more
openssl genrsa -out mykey.pem 1024 will actually produce a public – private key pair. The pair is stored in the generated mykey.pem file. openssl rsa -in mykey.pem -pubout > mykey.pub will extract the public key and print that out. Here is a link to a page that describes this better. EDIT: Check the examples section … Read more
cat ~/.ssh/id_rsa.pub or cat ~/.ssh/id_dsa.pub You can list all the public keys you have by doing: $ ls ~/.ssh/*.pub
Run the following command to retrieve the SHA256 fingerprint of your SSH key (-l means “list” instead of create a new key, -f means “filename”): $ ssh-keygen -lf /path/to/ssh/key So for example, on my machine the command I ran was (using RSA public key): $ ssh-keygen -lf ~/.ssh/id_rsa.pub 2048 00:11:22:33:44:55:66:77:88:99:aa:bb:cc:dd:ee:ff /Users/username/.ssh/id_rsa.pub (RSA) To get the … Read more
