- In most cases, we want to interact our python server (Flask/Django) with multiple clients over the web that uses JavaScript. This is a demonstration of how can you generate a signature in python and verity that signature in JavaScript and Vice Versa.
jsrsasign library test console:

Also if anyone is testing in Python3. The hash function does not takes String , instead it takes Bytes. simply add a ` b' ` before the HELLO WORLD string. e.g. message = b'HELLO WORLD'
That was helpful, thanks for making this video!
Crypto is depricated. Use Cryptodome instead. Simple replace all Crpyto packages to Cryptodome. e.g. `from Cryptodome.Signature import PKCS1_v1_5`
`from Cryptodome.Hash import SHA256` & `from Cryptodome.PublicKey import RSA`.
How to decrypt Signature in python.? Also how to decrease the length of Generated Signature? Moreover, if I am sending this Signature in url than it will create any issue? It will required url encoding?
Is there any new and secure way of implemeting the signatures?
If we need to digitally sign a file how do we do that. I have my private key stored in HSM
it says my library doesnt have this modules "signature" etc

Anum Sheraz thanks, i got it already running, but I will try that as well
how can i use digital signature on files (pdf for example)

lol.... why dont u share about PDF signer
