What is the size of the RSA signature in bytes?

Question

I am currently using Crypto ++ to create a signature for a data block. I expected the signature to be 20 bytes (SHA 1 Hash), as I realized that the signature is just an encrypted hash. But when checking with maxsignaturelength and signature length it seems like it's 192 bytes. This is normal?

Answer 1

Signature size is the size of the RSA module in bytes.
