Full Title or Meme
A signature on a digital document is designed to show that the document has not be altered and the identity of the key used to make the signature.
Solutions
- RSA signing with 3072 bit keys is good enough for TOP SECRET on 2015-08-19, but might not be included in post-quantum cryptography suites.
- See the wiki page Quantum Computing Threat for current status on post-quantum Cryptography.
- Curves Supported by OpenSSL can be discovered by keying (there will typically be many more that shown here)
