Frequently asked questions
What is Base64?
Base64 is a way of representing binary data using only text characters. It is widely used to embed images in HTML/CSS, send email attachments and transport data in APIs.
What is the difference between MD5 and SHA-256?
Both are hash (digest) functions. MD5 is old and fast, but it is not secure for passwords. SHA-256 is more modern and robust. Hashing is a one-way street: you cannot "decrypt" it.
Is my data sent to any server?
No. All encoding and hash computation are done in your browser.
