changing the pass phrase on a key from openssl
A while ago I created a key with openssl genrsa -aes256 4096 > server.key
. The process prompts for a pass phrase. I would now like to change that pass phrase, is that possible?
Use AES, e.g. AES256 instead of Triple DES:
openssl rsa -aes256 -in server.key -out newserver.key
If you have ssh-keygen
installed, this is simpler :
ssh-keygen -p -f server.key
openssl rsa -des3 -in server.key -out newserver.key
