I have an encrypted password I must decrypt as part of a challenge. Along with the password came a few UNENCRYPTED RSA private keys

From what I understand, all I need in order to decrypt the password is the private key, which I have. However I don't understand what software I need to use in order to decrypt the password using the private key. Does anyone know of an easy way to just plug in the encrypted password and unencrypted RSA private key to get a decrypted password or do I have to put in more effort?

  • $\begingroup$ How do I use this website? I found RSA decrypt but it asks for a key password. I don't have one. The output also tells me that the encrypted message length is invalid. $\endgroup$ Jul 19, 2022 at 12:10
  • $\begingroup$ You shouldn't need a key password if the key isn't encrypted. Try using a file as input instead. $\endgroup$ Jul 19, 2022 at 12:46

    $\begingroup$ I meant putting the encrypted password in a file as binary, but I should've been more specific. $\endgroup$ Jul 19, 2022 at 19:14
