I want to measure the guarantee of integrity of a digital signature.

I use RSA with a 4096 bit key, and SHA 256, and a passphrase. The level of security is going to depend on these three factors, yeah?

How do I measure how safe the digital signature is?

    How securely the private key is stored is one of the most significant indicators of the signature's integrity. – Ahmad Mar 5 at 9:48
  • You might be interested in something like the SOGIS Agreed Cryptographic Mechanisms. From their explanation why they consider which security algorithms strong enough, you can get an idea of the parameters involved. – mkl Mar 5 at 11:51
