OpenSSL "rsa -aes*" - Re-Encrypt RSA Keys
Q
How to re-encrypt an RSA key file using OpenSSL "rsa" command? I want to change the encryption password, and maybe change the encryption algorithm.

If you want to encrypt an existing RSA key file again,
you can use the "rsa -aes*" command as shown below:
C:\Users\fyicenter>\local\openssl\openssl OpenSSL> rsa -in my_rsa_des.key -out my_rsa_aes.key -aes128 Enter pass phrase for my_rsa_des.key: fyicenter writing RSA key Enter PEM pass phrase: fyicenter.com Verifying - Enter PEM pass phrase: fyicenter.com
Options used in this command are:
- "-in my_rsa_des.key" - Read the RSA private key file.
- "-out my_rsa_aea.key" - Save the output to a file.
- "-aes128" - Encrypt the output (RSA private key and public key).
- "fyicenter" - The password of the input key file.
- "fyicenter.com" - The password of the output key file.
