OpenSSL "genpkey rsa_keygen_bits:10240" - RSA Long Keys
How to generate a new RSA key pair with a longer key size using OpenSSL "genpkey" command?
✍: FYIcenter.com
If you need a new RSA key pair with a longer key size for testing purpose, you can use the OpenSSL "genpkey" command as shown below:
C:\Users\fyicenter>time The current time is: 18:43:27.27 C:\Users\fyicenter>\local\openssl\openssl OpenSSL> genpkey -algorithm rsa -out rsa_test.key -pkeyopt rsa_keygen_bits:10240 ........................................++ ................................................................................ ................................................................................ ................................................................................ ++ OpenSSL> exit C:\Users\fyicenter>time The current time is: 18:46:46.85
What this test tells us:
⇒ OpenSSL "genpkey -pkeyopt rsa_keygen_pubexp:3" - RSA Public Exponent
⇐ OpenSSL "genpkey rsa_keygen_bits:256" - RSA Short Keys
