OpenSSL "dsa -aes*" - Re-Encrypt DSA Keys

Q

How to re-encrypt a DSA key file using OpenSSL "dsa" command? I want to change the encryption password, and maybe change the encryption algorithm.

A

If you want to encrypt an existing DSA key file again, you can use the "dsa -aes*" command as shown below:

C:\Users\fyicenter>\local\openssl\openssl

OpenSSL> dsa -in my_dsa_2048_des.key -out my_dsa_2048_aes -aes128
read DSA key
Enter pass phrase for my_dsa_2048_des.key: fyicenter
writing DSA key
Enter PEM pass phrase: fyicenter.com
Verifying - Enter PEM pass phrase: fyicenter.com

Options used in this command are:

"-in my_dsa_2048_des.key" - Read the DSA private key file.
"-out my_dsa_2048_aea.key" - Save the output to a file.
"-aes128" - Encrypt the output (dsa private key and public key).
"fyicenter" - The password of the input key file.
"fyicenter.com" - The password of the output key file.
