perl - How can I decrypt encrypted files using a PEM private key?

问题描述:

I have files which have either been encrypted with a public key and the Blowfish algorithm, or a public key and the AES-256 algorithm.

I'm looking to put together a Perl script that would be able to use the private keys (which I do have) to decrypt the files.

The public and private key files are all in PEM format, and while I can find ways of reading the PEM files, and ways of decrypting data with a key, I haven't yet found a way of going from PEM -> key.

Any suggestions?

网友答案:

Isn't PEM just a base64 encoding (wrapped in --- BEGIN/END CERTIFICATE --- lines)? Try the Mime::Base64 module, or have a look at the source to the Convert::PEM module.
