Hello Mailinglist,
how does xmlSecKeyReadMemory() work? In what format should be the key?
Lets take the example rsakey.pem. This works:
xmlSecCryptoAppKeyLoad("Z:\\XmlSec\\examples\\rsakey.pem",
xmlSecKeyDataFormatPem, 0, 0, 0);
Now I'm trying to load the key from the RAM.
In the Konstruktor I have placed this code:
// The whole key of rsakey.pem in one line without the new lines:
const char
*cRsaKey2048Private="MIIEpQIBAAKCAQEAzFuwv0gXgmiSib1Py38Rkd/d6fOsujvGN09PBXInEiVWVtyyd3EHAU98+X3i"
// ...
// Convert key into binary:
int iBinLength = strlen(cRsaKey2048Private)*6/8+2; // Calulate buffer size
unsigned char *cBuffer = new unsigned char[iBinLength]; // Create Buffer
iBinLength = xmlSecBase64Decode(BAD_CAST cRsaKey2048Private,
cBuffer,
iBinLength); // Convert key from base64 to binary. Checked, in cBuffer
is the key in binary.
// Try to load the key... but oKey is still zero!
xmlSecKey *oKey = xmlSecKeyReadMemory(xmlSecKeyDataRsaId,
cBuffer,
iBinLength);
dsigCtx->signKey = oKey;
The error messages are:
func=xmlSecKeyDataBinRead:file=..\src\keysdata.c:line=349:obj=unknown:subj=id->binRead
!= NULL:error=100:assertion:
func=xmlSecKeyReadBuffer:file=..\src\keys.c:line=1184:obj=rsa:subj=xmlSecKeyDataBinRead:error=1:xmlsec
library function failed:
func=xmlSecKeyReadMemory:file=..\src\keys.c:line=1298:obj=rsa:subj=xmlSecKeyReadBuffer:error=1:xmlsec
library function failed:
I can go though the XmlSec source but it doesnt help much why this should be
"id->binRead!=NULL". The id comes from my input param xmlSecKeyDataRsaId, but
if this not work, what should I take instead?
Regards
Martin
