I have been searching some standards about cryptography best practices. I have found some articles and books but no official standard.

Do cryptography best practices standard exist?

  • Different standards exist in different domains. For use with credit cards, PCI DSS is a security standard that has some cryptographic elements in it. Financial transactions use ANSI/ISO standards. For use with US Government covered systems, NIST has a comprehensive set of standards. But there is not one overarching "Crypto Best Practice" that everyone adheres to. Aug 8 '17 at 2:29

The ISO provide standards on many things, including cryptographic procedures: ISO/IEC 19790:2012

I did a quick search on their site for cryptography and found a bunch of others including hash standards and secure financial services standards.

Only downside with ISO is that you often have to pay to get full access to the standards, so sometimes you'll have to do some googling to find a preview.

Hope this helps.

Your question is a little vague. Not sure if you want to develop your own crypto (not recommended), implement it in a specific language (a question for stackoverflow, probably), or if you want just a set of standards.

For the latter: NIST Cryptographic Standards and Guidelines Development Process
