base64 - What is base 64 encoding used for? - Stack Overflow Base64 is also used when communicating with government Fiscal Signature printing devices (usually, over serial or parallel ports) to minimize the delay when transferring receipt characters for signing Base64 is used to encode binary files such as images within scripts, to avoid depending on external files
string - Base64 length calculation? - Stack Overflow 41 For reference, the Base64 encoder's length formula is as follows: As you said, a Base64 encoder given n bytes of data will produce a string of 4n 3 Base64 characters Put another way, every 3 bytes of data will result in 4 Base64 characters
powershell - How to decode a Base64 string? - Stack Overflow Base64 encoding converts three 8-bit bytes (0-255) into four 6-bit bytes (0-63 aka base64) Each of the four bytes indexes an ASCII string which represents the final output as four 8-bit ASCII characters The indexed string is typically 'A-Za-z0-9+ ' with '=' used as padding This is why encoded data is 4 3 longer Base64 decoding is the inverse process And as one would expect, the decoded
How do I convert a byte array to Base64 in Java? Okay, I know how to do it in C# It's as simple as: Convert ToBase64String(byte[]) and Convert FromBase64String(string) to get byte[] back How can I do this in Java?
