About MD5

MD5 (Message Digest 5) is a widely used cryptographic hash function that produces a 128-bit hash value. It was designed by Ronald Rivest in 1991 as an improvement over MD4. Although MD5 was once considered secure, it has since been found to have significant vulnerabilities, including the ability to generate collision attacks, making it unsuitable for cryptographic purposes.

尽管存在安全漏洞，但 MD5 仍用于非安全应用程序，例如文件完整性检查、错误检查系统和需要兼容性的遗留系统。请务必注意，MD5 不应用于需要强安全性的应用程序，例如密码哈希或数字签名。
