"There is a well understood best practice in software development that
developers should not attempt to write their own cryptographic algorithms
because of the complexity, lack of peer review, and value of that which the
cryptographic functions are protecting. Developers, in contrast, routinely
write one-off identity solutions that are never peer reviewed by a wider
audience. This identity information is propagated and integrated throughout
software systems and used as a basis for making security decisions about
access control to critical resources and the confidentiality of personal and
business data."

ly/207.html?branch=1&language=1
Even if the crypto is implemented correctly, there are usually problems in
the identity implementation which is the basis for access control decisions,
anyhow. So developers should not write that either.
