Hi ,
We are porting our Application from openssl 1.0.1 to openssl
3.0. in related to this activity we require to access the variable 'ex_kusage'
pointed by X509
But there are no set utilities available to access this variable. Only
X509_get_key_usage Is available.
Our code for 1.0.1 is as below. Please suggest the right way to achieve this.
ASN1_BIT_STRING *usage;
662 x509->ex_kusage = 0;
663
664 if((usage=(ASN1_BIT_STRING *)X509_get_ext_d2i(x509, NID_key_usage,
NULL, NULL)))
665 {
666 if(usage->length > 0)
667 {
668 x509->ex_kusage = usage->data[0];
669 if(usage->length > 1)
670 x509->ex_kusage |= usage->data[1] << 8;
671 }
672 else
673 x509->ex_kusage = 0;
674 ASN1_BIT_STRING_free(usage);
675 }
Regards,
Sunil
