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

Questions
1

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?

so I tried putting modulus and exponent from extracting with RSA Key Converter - Superdry Developer
encrypted data is then processed into bytes to base64 block but unfortunately the output doesn’t work…

then I just tried/used the output from Online RSA Encryption, Decryption And Key Generator Tool | Devglan and it works without any issue.

so I need some help in how do I do it in OB2… be it with modulus and exponent.

hmm is the bytearray to base64 correct block/method after the encrypted output of RSA PKCS1PAD2 block? I’m confused…
