Bleichenbacher-attack test vectors I was trying to understand the Bleichenbacher-attack. I went through the paper of Bleichenbacher to understand it bit more. However I tried to get some test vectors to simulate this attack locally but couldn't find it.

Can some please help me in getting smaller test vectors so that I can do some hands on?
As mentioned by j.p., the original attack has been (quite significantly) improved in 2012 and some great tutorials are available online, often demonstrated with example.

If you want a more exhaustive list of test vectors, I suggest you take a look at Project Wycheproof, a tool developed by members of Google Security Team, designed to find vulnerabilities in cryptographic libraries. The idea behind this project is to use a large database of test vectors allowing to verify primitives conformance and check if they are vulnerable to some well known attacks.

You can find test vectors for RSA PKCS#1v1.5 for different key size (2048, 3072, 4096).

One of the maintainer of this project is Daniel Bleichenbacher himself (also Thai Duong, Emilia Kasper and Quan Nguyen), so test vectors should be valid!
