Common Mistakes to Avoid

⚠️

Thinking Base64 is encryption

Solution: Base64 is encoding, not encryption. Anyone can decode it. Use proper encryption for security.

⚠️

Not handling padding correctly

Solution: Valid Base64 ends with = or == for padding. Don't remove these characters.

⚠️

Using Base64 for passwords

Solution: Never store passwords in Base64. Use proper hashing algorithms like bcrypt or Argon2.
