WebDec 9, 2024 · Meanwhile, another algorithm supported by JWT, known as HS256, utilizes HMAC with SHA-256 to sign the JWT. The main difference is that HS256 uses Symmetric Key Encryption. This means that both its signing and verification are done with one single key. This will be the key to the exploit. WebThe idea is to make the exponent a large multiple of p − 1 by making it a number with very many prime factors; generally, we take the product of all prime powers less than some limit B. Start with a random x, and repeatedly replace it by as w …
