'd41d8cd98f00b204e9800998ecf8427e' is the MD5 of the empty string and Subversion has special handling of that checksum. Instead of setting the digest directly you could call svn_checksum_clear and then svn_checksum_to_cstring_display to check that you get the digest you expect. For the '568554e2bf0fc50aa347777731081a80' I assume you could call svn_checksum and pass in the data that gives that checksum. -- Certified & Supported Apache Subversion Downloads: http://www.wandisco.com/subversion/download
