WebJul 12, 2011 · 1 Answer. You are right, the RSA signature size is dependent on the key size, the RSA signature size is equal to the length of the modulus in bytes. This means that for a "n bit key", the resulting signature will be exactly n bits long. Although the computed signature value is not necessarily n bits, the result will be padded to match exactly n ... WebNov 1, 2024 · From a formatting standpoint, the minimum signature size for RS256 (RSASSA-PKCS1-v1_5 with SHA-256) would be $2+8+1+19+32=62$ bytes, that is a 489-bit public modulus. That would be way too small to be secure, though. 2048-bit is considered the baseline for new applications.

And, when I use the chip to generate a signature, it is indeed 64 bytes in length. However, when I use openssl, the signature is 71 bytes in length. The beginning of the signature seems to be some kind of prefix, but I can't find any data about what that is.
