Detailed Description
Base64 decodes data using DUDE.
Base64 encodes data per RFC 4648, Base 64 Encoding.
Constructor & Destructor Documentation
◆ Base64Decoder()
|
inline |
Construct a Base64Decoder.
- Parameters
-
attachment a BufferedTrasformation to attach to this object
- See also
- IsolatedInitialize() for an example of modifying an encoder after construction.
Member Function Documentation
◆ IsolatedInitialize()
|
virtual |
Initialize or reinitialize this object, without signal propagation.
- Parameters
-
parameters a set of NameValuePairs used to initialize this object
IsolatedInitialize() is used to initialize or reinitialize an object using a variable number of arbitrarily typed arguments. IsolatedInitialize() does not call Initialize() on attached transformations. If initialization should be propagated, then use the Initialize() function.
The default decoding alpahbet is RFC 4868. You can change the to RFC 4868 web safe alphabet by performing the following:
int lookup[256];
const byte ALPHABET[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-_";
Base64Decoder::InitializeDecodingLookupArray(lookup, ALPHABET, 64, false);
Base64Decoder decoder;
AlgorithmParameters params = MakeParameters(Name::DecodingLookupArray(),(const int *)lookup);
decoder.IsolatedInitialize(params); - See also
- Base64URLDecoder for a decoder that provides the web safe alphabet, and Base64Encoder::IsolatedInitialize() for an example of modifying an encoder's alphabet after construction.
Reimplemented from BufferedTransformation.
