Hi Gary,
A SecByteBlock is a type def of SecBlock<byte> from secblock.h. I do
recall that a SecByteBlock is missing from the online documentation,
but SecBlock is present. See
http://cryptopp.com/docs/ref/class_sec_block.html.
Line 262 of secblock.h is of interest:
iterator begin() {return m_ptr;}
SecBlock also provides some operator void* (casts) to get at the m_ptr member.
