DWORD dwFlags, Format of the resulting formatted string. If you are using a Windows system, there is no built-in command to directly perform Base64 encoding and decoding. 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. DWORD cbBinary, Number of elements in the pbBinary array. It means encoding the username and password using base 64. Where dXNlcm5hbWU6cGFzc3dvcmQ is Base64-encoded 'username:password' (literally). const BYTE *pbBinary, Pointer to the array of bytes to be converted into a string. In HTTP Basic authentication, the 'password:username' is encoded in Base64. Therefore, if you are not sure that your Base64 string is a PDF, use the Base64 to file converter since it is capable of displaying various file types. If the function fails, it returns zero (FALSE). The Base64 to PDF converter will force the decoding result to be displayed as a PDF file, even if it is a different file type. ![]() ![]() If the function succeeds, the function returns nonzero (TRUE). If you need to work with Base64 format, then this site is built for you Feel free to use our online tools to decode or encode your data. Presumably we also have to specify the dll in the asn file?Ĭ++ function to convert an array of bytes into a formatted string. Tried to use the cryptBinaryToStringA operation in the crypt32.dll but not sure how to define the parameters: a couple are 'pointers'. We're using U9.2 - before $encode/$decode were implemented & we'd like to decode base64 we're receiving. Windows base64 Encoding and Decoding Using certutil the Operating System Commands signature)? If I understand it correctly then the Certutil.exe can decode Base64 data. ![]() I know there is a way to handle a pointer to a string, but that is different (AFAIK).īut why not use a default Windows command line tool that can do this, and call it from Uniface (with e.g. I have never tried to call a parameter that is a pointer to an array of bytes. I think you would need CryptStringToBinaryA to decode Base64.Īnyway, looking at the interface definition I don't think that there is a straight forward way to call the mentioned function with a C Call-Out signature. Are sure that the CryptBinaryToStringA function is decoding data? If I read it correctly then it is encoding or converting data to a formatted string (like e.g.
