Base64 represents binary data using only letters, digits and a few symbols. It is common in email attachments, data URLs and APIs. It is an encoding, not encryption: anyone can decode it.
Frequently asked questions
Is Base64 secure?
No. Base64 is an encoding, not encryption, so it must not be used to protect secrets.
Does it handle Unicode?
