SEC_DerSignData problem

[Jingyu Liu]

Hi all,



I have following piece of program, it just encrypts some data with
SEC_DerSignData, and then

decode it. It appears that function SEC_DerSignData succeeds, but
SEC_ASN1DecodeItem

always returns DER_BAD error code. What's wrong with my code? Please assume
that all

variables are initialized correctly.



Thank you very much!

SECItem  dataDER;

char *data = "test data";

CERTSignedData signedData;



if (SEC_DerSignData(pArena, dataDER, (unsigned char *)data, strlen(data) +
1, pPrivateKey,

     SEC_OID_PKCS1_MD5_WITH_RSA_ENCRYPTION) != SECSuccess)

   printf("DerSignData error");





PORT_Memset(&signedData, 0, sizeof(signedData));

if (SEC_ASN1DecodeItem(pArena, &signedData,

    SEC_ASN1_GET(CERT_SignedDataTemplate), &dataDER) != SECSuccess)

   printf("DecodeItem error");
