OWASP Top 10:2021 - A02 Cryptographic Failures
Cryptographic failures refer to the improper use, implementation, or management of cryptographic systems. These issues often result in unauthorized exposure of sensitive data like passwords, credit card numbers, or personal records. In the OWASP Top 10 – 2021, this category replaced the broader ‘sensitive data exposure’ from the 2017 list, with a sharper focus on the misuse or failure of cryptographic mechanisms.
