Frequently Asked Questions
Q: Is Base64 secure for data privacy?
A: No, Base64 is only an encoding mechanism, not encryption. Anyone can decode a Base64 string instantly. For security or hashing purposes, use modern standards like AES or SHA-256.
Q: What kind of text strings can I encode?
A: You can encode virtually any text, data object configurations, structured JSON formats, query strings, or standard web URLs without compatibility issues.
Q: How do I identify a standard Base64 string?
A: Base64 strings generally contain character sets ranging from A-Z, a-z, 0-9, along with +, /, and frequently end with one or two padding characters (= or ==).
