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.
