MD5 Encrypt

Is this actually encryption?

Not quite, although "MD5 encrypt" is a popular way to describe it. MD5 (Message Digest Algorithm 5) is a hashing function that converts any input into a fixed 32-character hexadecimal digest. Unlike real encryption, there is no key and no way to reverse the process to get back the original text.

Note: MD5 is not suitable for encrypting sensitive data or storing passwords. It is vulnerable to collision and rainbow table attacks. Use AES for encryption and bcrypt or Argon2 for password hashing.
