The exception that is thrown is a boost::iostreams::zlib_error. The error code that's found within is -3 which is defined as Z_DATA_ERROR. Here is another bit: If I remove the zlib compressor/decompressor (leaving only the encrypt/decrypt) and step through it looks like everything is working fine until the last buffer the decryption routine sees -- which it is unable to decrypt back to plain text. Stepping through the encryption routine seems OK to me though (it appears to properly encrypt everything OK). Note again that I can do the reverse: Remove the encrypt/decrypt but keep the compress/decompress and it works fine. ------------------------------

Could you please report what happened when you tried Ken's suggestions about either catching the exception or using a debugger to narrow down the cause of the problem?
