Stephen, Based on the code in test.cpp for GzipFile and GunzipFile, I have always used the following, and it should work for you:
// Gzip contents of plaintext into gzip_text; StringSource(plaintext, true, new Gzip(new StringSink(gzip_text))); // Ungzip contents of gzip_text into unzip_text; StringSource(gzip_text, true, new Gunzip(new StringSink(unzip_text))); Maybe I am missing something in your requirements? (I have been pretty much following your whole thread.) You can also string these together, so if you want to gzip then B64 encode, you could: StringSource(plaintext, true, new Gzip(new Base64Encoder(new StringSink(b64_text)))); And then to undo it back to plaintext, you do: StringSource(b64_text, true, new Base64Decoder(new Gunzip(new StringSink(unb64_text)))); Hope this helps, Scott Barnhart -----Original Message----- From: Stephen torri [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 18, 2003 4:38 PM To: cryptopp Subject: Gzip & Gunzip code: Correct or rubbish I decided to work on get my encrypt and decrypt methods in stages. The first stage is to get the plain text string compressed and decompressed correctly. Gcc:3.2.3 Crypto:5.1 Compress: string gzip_text; Gzip aes_compressor2 (new StringSink (gzip_text)); StringStore(plaintext).TransferTo(aes_compressor2); string unzip_text; Gunzip aes_decompressor2 (new StringSink (unzip_text)); StringStore(gzip_text).TransferTo(aes_decompressor2); I got this from searching the archive of the mailing list. Shame we do not have a directory of example programs. Is this right? So far I believe it does not because what I get in 'unzip_text' is rubbish.
