How to generate RSA keys and encrypt/sign messages using openssl/cygwin

[rainbacknet]

That bash script is utterly terrible... a ton of redundant nonsense, unused commandline options, and completely unnecessary use of files with dd. I would recommend using read, or simply cat, for much cleaner input. Use variables instead of files to store the key. Using a file also poses a security risk. base64 takes either stdin or a file; here you've specified both, so the stdin-as-file is ignored.
