#Base64 decode string code
It may have also masked problems with code not properly escaping POST variables. So the original code was unfortunately not fully compatible with the spec or other implementations. However, RFC 3548 states that characters not in the Base64 alphabet should either be ignored or cause the implementation to reject the encoding and RFC 2045 says they should be ignored. This will also save many people considerable It's not exactly the Base64 spec,īut it is completely compatible with it (the spec says that spacesĪre invalid). base64encode(object, newlinesFALSE) base64decode(encoded). Terraform uses the standard Base64 alphabet as defined. Encodes or decodes a character string or raw vector to or from Base64 encoding. Base64 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. When Base64 gets POSTed, all pluses are interpreted as spaces. base64decode takes a string containing a Base64 character sequence and returns the original string. Base64 encode your data without hassles or decode it into a human-readable format.
#Base64 decode string plus
It would seem from the comment preceding the code which was removed that the treatment of the space as if it were the plus sign was actually intentional at one time: Therefore 64 characters are chosen that are both. The CVS log indicates that this change was made to fix bug #34214 (base64_decode() does not properly ignore whitespace). Base64 encoding schemes are used when binary data needs to be stored or transferred as textual data. You can see what happened with a diff to branch point 1.43 at: This function takes a single argument which is the string to decode and returns the decoded data. decodebase64 ( str ) Decode a base64 string by calling the decodebase64 () function.
Use the Encode module to select the byte encoding you want. The Base64 module provides for the encoding ( encode64, strictencode64, urlsafeencode64 ) and decoding ( decode64, strictdecode64, urlsafedecode64 ). To follow up on Starson's post, PHP was changed to no longer treat a space as if it were a plus sign in CVS revision 1.43.2.1, which corresponds to PHP 5.1.0. The base64 encoding is only defined for single-byte characters. In JavaScript there are two functions respectively for decoding and encoding Base64 strings: btoa (): creates a Base64-encoded ASCII string from a 'string' of binary data ('btoa' should be read as 'binary to ASCII').

You can use the btoa () method to encode and transmit data which may otherwise cause communication problems, then transmit it and use the atob () method to decode the data again. Guru A virtual teacher who reveals to you the great secrets of Base64 The atob () function decodes a string of data which has been encoded using Base64 encoding.
