Ah I missed that part. The following should help: http://www.gdal.org/cpl__string_8h.html: char * CPLBinaryToHex (int nBytes, const GByte *pabyData) CPL_WARN_UNUSED_RESULT Binary to hexadecimal translation. More... GByte * CPLHexToBinary (const char *pszHex, int *pnBytes) CPL_WARN_UNUSED_RESULT Even more compact with base64 encoding: char * CPLBase64Encode (int nBytes, const GByte *pabyData) CPL_WARN_UNUSED_RESULT int CPLBase64DecodeInPlace (GByte *pszBase64) > > Norman, thanks for the links.
