Decoders for "Private Keys":
NEVER upload or disclosure your private key on a website or online service. You should use a local method of decoding the private key, one should never disclose the private key to anyone, and definitely not the internet, as this is literally the "key" to the castle. If one obtains your private key.. they can decrypt ALL your traffic, and thus if ever compromised, should be deleted and regenerated.
The following local commands using the openssl commands from the OpenSSL package/module, you can decode a private key to learn more about it.
(Installed by default on Unix/Linux, can be downloaded and installed for just about every platform)
openssl rsa -in <encrypted_private.key> -out <decrypted_private.key>openssl rsa -in <private.key> -text -noout
