Obviously, Crypto++ has them just like Unix and Linux. Also see https://www.cryptopp.com/wiki/Pipelining .
In a pipeline, data flows from a source to a sink. In between there are filters which transform the data. The Crypto++ code above is a lot like the following Unix commands: cat plain.txt | enc -k key -m ecb | hex -e > cipher.txt The StreamTransformationFilter is the heavy lifter. It accumulates incoming plain text. It adds padding to the final block. It also accumulates cipher text until you retireve it. Its a very complex filter. Another filter is the HexEncoder. Its easy to understand its operation. You might be interested in https://www.cryptopp.com/wiki/Init-Update-Final. It kind of presents Crypto++'s objects in a Java-esque kind of way.
