Simple Message Signature
This website allow you to use RSA based signatures for your messages very simply.
You just need to generate a key pair and sign a message in one click!
The signatures are generated with this model, so you can check them by yourself if you want....
message --->(sha256)--->(RSA encryption with private key)--->(base64 encode)---> Signature
To check the signature just check if this two lines are equals
message --->(sha256)--> hash
Signature --->(base64 decode)--->(RSA decrypt with public key)---> original_hash
Formatting of messages
Messages with the signature are constructed on the following model:
This is the original message
The original message can be on multiplte lines
Some text to explain how/where you can check the signature
SIGNATURE:(Here goes the signature)
Note that a blank line is added after the original message
