These characters are: Note: There is also a 65th character (=) , which serves a special meaning and it's called a padding character. So if you have a Base64 string and want to identify its MIME type using file signatures you don't need to decode the Base64. That's exactly why we're converting it. As usual, when it comes to computers, numbers are represented in powers of 2. Again, the decode() method works with a byte array and decodes the Base64 String into the original one: Note: Three special characters are available in this schema: +, /, =. Base64 is a binary-to-text encoding scheme that represents binary data in a printable ASCII string format. Use our free online tool to encode any text or file data to Base64 encoded format. However, file signatures are not 100% reliable and you can easily encounter false positives. Best Java code snippets using java.util. It represents binary data in a printable ASCII string format by translating it into a radix-64 representation.

How do I know the type of the file (e.g jpeg)? In general, a base 64-encoded string could contain absolutely any data, so there is no way to know its file type. How to get MIME-TYPE from Base 64 String? Alternatively, you can use the encodeBase64String() method, which will return a String, instead of a byte array: In the same vein, the Base64 class is used as a decoder as well. Get the decimal values of these binary chunks: In the end, we're left with the String QUJDMTIz - the Base64 representation of ABC123. While it does "obscure" the data to a degree, it's not a secure format by any means. For example, let's say we have a String - ABC123 that we'd like to encode in Base64. If the String's length is not divisible by 3 (the 8-bit representation won't be able to bundle up in 6-bit groups), padding will be added in the form of = at the end: The Base64 is a factory class from which we'll retrieve different implementations/variations of the encoder.
