Common Mistakes to Avoid

Treating Base64 as a secure encryption mechanism. Base64 is only a data format and is easily decoded by anyone without any keys.
Including spaces or hidden carriage returns, which modify the resulting Base64 stream significantly.

Frequently asked questions

What is Base64 encoding?

Base64 is a binary-to-text encoding scheme that translates data into a set of 64 characters (A-Z, a-z, 0-9, +, /) to ensure safe data transfer over text-only channels.

Is Base64 secure for passwords?

No. Base64 is a formatting scheme, not encryption. Anyone can decode a Base64 string instantly. Never use it to store passwords or sensitive credentials.

What do the '=' characters at the end mean?

The '=' character is used as padding to ensure the encoded string's length is a multiple of 4 bytes, as required by the Base64 standard.
