Every character in a Base64 string contains 6 bits of information, because there are 64 possible values for the character, and it takes 6 powers of 2 to reach 64. Only the first 22 characters matter.Īn MD5 hash is a 128-bit value. The padding adds no useful information and can be discarded. Many Base64 algorithms will also append 2 characters of padding when encoding an MD5 hash, bringing the total to 24 characters. Packs of 6 bits (6 bits have a maximum of 64 different binary values) are converted into 4 numbers (24 = 4 * 6 bits) which are then converted to their corresponding values in Base64.An MD5 value is always 22 (useful) characters long in Base64 notation. These three bytes are joined together in a 24 bit buffer producing the binary sequence '010011010110000101101110'. In the above quote the encoded value of Man is TWFu. TWFuIGlzIGRpc3Rpbmd1aXNoZWQsIG5vdCBvbmx5IGJ5IGhpcyByZWFzb24sIGJ1dCAuLi4= This is represented as an ASCII byte sequence and encoded in MIME's Base64 scheme as follows: ' Man is distinguished, not only by his reason, but. Here's a quote snippet from Thomas Hobbes's Leviathan: Other variations, usually derived from Base64, share this property but differ in the symbols chosen for the last two values an example is the URL and filename safe 'RFC 4648 / Base64URL' variant, which uses '-' and '_'. For example, MIME's Base64 implementation uses A-Z, a-z, and 0-9 for the first 62 values, as well as '+' and '/' for the last two. This combination leaves the data unlikely to be modified in transit through systems such as email, which were traditionally not 8-bit clean. The general rule is to choose a set of 64 characters that is both 1) part of a subset common to most encodings, and 2) also printable. The particular choice of characters to make up the 64 characters required for Base64 varies between implementations. The Base64 term originates from a specific MIME-content transfer encoding.

From now on, you don't need to download any software for such simple tasks.īase64 is a generic term for a number of similar encoding schemes that encode binary data by treating it numerically and translating it into a base-64 representation. Read our privacy policy below for more details. We do not keep or inspect the contents of the submitted data or uploaded files in any way. We delete uploaded files from our servers immediately after being processed and the resulting downloadable file is deleted right after the first download attempt or 15 minutes of inactivity (whichever is shorter). Currently, this mode supports only the UTF-8 character set.Īll communications with our servers come through secure SSL encrypted connections (https). Live mode: When you turn on this option the entered data is decoded immediately with your browser's built-in JavaScript functions, without sending any information to our servers.This option is useful if you intend to decode multiple independent data entries that are separated by line breaks. Prior to decoding, all non-encoded whitespaces are stripped from the input to safeguard the input's integrity. Decode each line separately: The encoded data usually consists of continuous text, so even newline characters are converted into their Base64 encoded forms.Note that this is irrelevant for files since no web-safe conversions need to be applied to them. This information is used to convert the decoded data to our website's character set so that all letters and symbols can be displayed properly.

It is usually UTF-8, but can be many others if you are not sure then play with the available options or try the auto-detect option. Character set: In case of textual data, the encoding scheme does not contain the character set, so you have to specify which character set was used during the encoding process.

Base64 is used commonly in a number of applications including email via MIME, as well as storing complex data in XML or JSON. This encoding helps to ensure that the data remains intact without modification during transport. Base64 encode your data without hassles or decode it into a human-readable format.īase64 encoding schemes are commonly used when there is a need to encode binary data, especially when that data needs to be stored and transferred over media that are designed to deal with text. 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.
