I did the same exact this as you have shown here, just that the constant string is json and I’m not getting correct output…

for my current status:

How to RSA encrypt correctly with a public key base64 encoded?

I wanna encrypt some data with RSA public key and then encode with Base64. How can I do it in OB2? I have seen the RSA encrypt and the RSA PKCS1PAD2 blocks but I don’t know what is modulus and exponent… and what next block should be used to encode encrypted output to Base64. How can I encrypt the data with my public key which is base64 encoded to a Base64 encoded and RSA PKCS1PAD2 encrypted output? can someone help please?
