OpenSSL "genpkey -des" - DES Encrypt RSA Keys

Q

How to generate a new RSA key pair and encrypt the output with a DES password using OpenSSL "genpkey" command?

✍: FYIcenter.com

A

If you want to secure your new RSA private key with a DES encryption, you can use the OpenSSL "genpkey -des" command as shown below:

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

OpenSSL> genpkey -algorithm rsa -out my_rsa_des.key -des
..................................................++++++
..++++++
Enter PEM pass phrase: fyicenter
Verifying - Enter PEM pass phrase: fyicenter

Options used in this command are:

"-algorithm rsa" - Use RSA algorithm to generate private key and public key.
"-out my_rsa_des.key" - Save output (the new RSA private and public key) in a file.
"-des" - Encrypt the output with DES algorithm.
"fyicenter" - The password of the DES encryption.

OpenSSL "genpkey -pkeyopt rsa_keygen_pubexp:1" - Bad RSA Key
Can I use 1 as the public exponent to generate an RSA private key? No. Using public exponent of 1 will generate identical RSA private key and public key as shown below: C:\Users\fyicenter>\loc al\openssl\opensslOpenSSL> genpkey -algorithm rsa -out rsa_test.key -pkeyopt rsa_keygen_bits:... 2018-01-06, ∼3416🔥, 0💬

What will happen if I use 2 as the public exponent to generate an RSA private key? OpenSSL will run forever, if you use 2 as the public exponent to generate an RSA private key, because OpenSSL can no find any private exponent to meet the RSA requirements.
