The encrypted data is a good candidate to Base64-encode though, if you need to store the encrypted data in a text file. If you need to hide your data, use encryption. Numerous tools are available to decode the data without the need for any key. If you would like to obfuscate the data, then Base64 will offer you a very poor security mechanism. Also, mail and file systems can now cope with 4 byte words containing millions of characters. thing about it is that it preserves the integrity as well as the conciseness of your binary data in the online environment. Base64 encoded data might save you some trouble there. Some of those settings may contain characters that aren't allowed in the file, like encrypted passwords, html snippets or other arbitrary data. Say for example that you have an xml, unix config or java property file with settings for an application. Well, it's often used when you already have binary data and you still want to store the data in a 7 bit environment. If the last group contains two characters the encoding will have just one = character. If the last 24 bits contain only one character, that character is encoded into two characters and the last two spots will be padded with the characters =. The = character is a padding character added at the end of the encoding in case the input data is not dividable by 3. 6 bits can contain 2^6 combinations, which is 64, thus the name Base64. Each section of 6 bits is then translated into a new character in the range a-zA-Z0-9+/. Now, the resulting 24 bits are split into four sections of 6 bits instead. Since 8 bit characters consist of, well, 8 bits, Base64 encoding groups the characters into groups of three 8 bit characters, yielding 24 bits. The original RFC for Base64 was the Privacy-enhanced Electronic Mail (PEM) RFC 989 but now numerous variations exists, as well as RFC:s, like the RFC 1421, RFC 2045, RFC 3548, RFC 4848 and several other as well. This was mostly used in transfering of data across 6 or 7 bit connections. Base64 encoding schemes are commonly used when there is a need to encode binary data, especially when. Base64 encode your data without hassles or decode it into a human-readable format. In short, Base64-encoding is a way to encode 8 bit character data in a series of 6 bit characters. Meet Base64 Decode and Encode, a simple online tool that does exactly what it says: decodes from Base64 encoding as well as encodes into it quickly and easily.
