In the HTTPS era, front-end password encryption: MD5 is outdated?

When building a secure login system, many front-end developers will hesitate to have MD5 encryption on their passwords. Especially today when HTTPS is popular, this kind of question is more common. This article will answer this question.

Question: In HTTPS environment, do I still need an MD5 encryption password when logging in at the front end?

Answer: No front-end MD5 encryption is required. Although MD5 generates a one-way hash value, it cannot effectively prevent password leakage. Even if the front-end is encrypted and transmitted, the attacker can still intercept the encrypted password. Since MD5 is irreversible, the backend can only store the encrypted password and cannot be decrypted. This means that the man-in-the-middle attacks may still obtain encrypted passwords and obtain the original password through brute force (such as using rainbow tables). Therefore, front-end MD5 encryption not only does not help improve security, but instead increases unnecessary complexity.

The best practice is to pass password encryption to the backend for processing. The front-end simply needs to securely transmit the plaintext password to the back-end. The HTTPS protocol ensures the security of data transmission and prevents eavesdropping and tampering, which is the key to ensuring login security.
