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. The decoder rejects data that contains characters outside the base64 alphabet. Also, mail and file systems can now cope with 4 byte words containing millions of characters. The encoder does not add any line feed (line separator) character. Base64 encoded data might save you some trouble there. The string should conform to the Base64 Data Encodings specification (RFC 4648). What is the use of Decoded Image Reverse Base64 : Convert image base64 to the actual image for use in html, css, javascript, etc. Some of those settings may contain characters that aren't allowed in the file, like encrypted passwords, html snippets or other arbitrary data. Click on the filename link to download the image. Say for example that you have an xml, unix config or java property file with settings for an application. byte decodeData Base64.getMimeDecoder().decode(encodedData) (new String(decodeData, StandardCharsets.UTF8)). 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. In other words, it is a tool that converts Base64 to original data. ![]() 6 bits can contain 2^6 combinations, which is 64, thus the name Base64. The Base64 Decode Online is a free decoder for decoding online Base64 to text or binary. 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. Plain Text - Only Base64 data Data Url - Base64 in data url format (data: charset base64,) HTML IFarme Tag - HTML.This was mostly used in transfering of data across 6 or 7 bit connections. Text types have the charset parameter set to 'utf-8' by default. short, Base64-encoding is a way to encode 8 bit character data in a series of 6 bit characters. The built-in table is small but on unix it is augmented by the local system's MIME-info database or mime.types file (s) if available under one or more of these names: On Windows, MIME types are extracted from the registry. String textEncoded = 8.EncodeBase64(null) String textDecoded = 8.DecodeBase64(textEncoded) String textEncoded = 8.EncodeBase64("test1.") Public static string DecodeBase64(this encoding, string encodedText)īyte textAsBytes = 64String(encodedText) Use the MIME Multipart Encoder and Decoder. Public static string EncodeBase64(this encoding, string text)īyte textAsBytes = encoding.GetBytes(text) ![]() Remark: Remember that to use Extension Method you have to (!) import the namespace with using keyword (in this case using ).Ĭode: namespace Another improvement is failing gracefully with null result for null entry - it's very useful in real life scenarios and supports equivalence for X=decode(encode(X)).Rationale is that someone may need to support different types of encodings (not only UTF8). uses Extension Methods for Encoding class. ![]() I'm sharing my implementation with some neat features:
