I have RSA encrypted private key with passphrase how do I decrypt the private key file

Question

Basically I want to do this in command in java

openssl rsa -in enc_private.key -out private.key -passin pass:passphrase_xyz

beginning of my encrypted key file looks like this

-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: DES-EDE3-CBC,59e5e15b3d9474e6

please assist.

I couldn't find any solution for it either, for now I have added script which is called from dockerfile to execute these steps. — Manth, Feb 23 '23 at 23:10

You could use

Runtime.getRuntime().exec("openssl rsa -in enc_private.key -out private.key -passin pass:passphrase_xyz");

Maybe a bash or PowerShell script would be better suited?

I ran this command form docker file but suggestion was to make it part of application once it is started so I guess will settle for above suggested approach. I was trying to understand if there is a way to achieve this using java libraries. – Manth Feb 16 '23 at 14:24
