Note that it still rejects incorrectly-padded input. ![]() This method accepts both correctly-padded and unpadded input. The alphabet uses - instead of + and instead of /. This method complies with Base 64 Encoding with URL and Filename Safe Alphabet in RFC 4648. How can I embed Base64 encoded resource directly into HTML, XML and CSS files? Returns the Base64-decoded version of str. Base64 encoding can be helpful when fairly lengthy identifying information is used in an HTTP environment. If the number of bytes are not in numbers of three, then padding is used = for 1 byte and = for 2 bytes.Ĭonsult wikipedia for more information. This encoding is designed to make binary data survive transport through transport layers that are not 8-bit clean, such as mail bodies. Those 6 bits form a number corresponding to the index in the character set supported by Base64 (A-Z, a-z, 0-9, + and /). base64encode (PHP 4, PHP 5, PHP 7, PHP 8) base64encode Encodes data with MIME base64 Description base64encode ( string string ): string Encodes the given string with base64. The resulting buffer of 3 bytes is then broken in 4 packs of 6 bits each. How does Base64 encoding work?īytes forming the data are broken into buffers of 24 bits (3 bytes at a time). Basics of Base64 Encoding A base64 string is pretty easy to identify: VGhpcyBpcyB3aGF0IGJhc2U2NCBsb29rcyBsaWtlIGluIHRoZSB3aWxkLgo There are 64 characters in the Base64 alphabet, and an encoded string will contain a mixture of uppercase and lowercase letters, numbers, and sometimes an or two (never more than two) at the end. Concrete examples would be sending images in an XML file or in an email attachment. Base64 Encoding Explained Why do I need Base64 encoding Base64 is an encoding scheme used to represent binary data in an ASCII format. This is useful when binary data needs to be sent over media that are usually designed to handle textual data. The purpose of using base64 to encode data is that it translates any binary data into purely printable characters. The cipher object cannot be used after the final() method is. Message Digester (MD5, SHA-256, SHA-512)īase64 is an encoding scheme used to represent binary data in an ASCII format. If no encoding is provided, then a Buffer is returned. ![]() Credit Card Number Generator & Validator. ![]()
