crypto weakness #43

Weakness Breakdown


Definition:

This weakness involves creating non-standard or non-tested algorithms, using weak algorithms or applying cryptographic algorithms incorrectly. Algorithms that were once considered safe are commonly later found to be unsafe, as the algorithms were broken.

Warning code(s):

DES only supports a 56-bit keysize, which is too small given today's computers.

File Name:

libressl/src/libressl-2.5.5/ssl/ssl_algs.c

Context:
