NAME
       X509_get0_uids, X509_ACERT_get0_issuerUID - get certificate and
       attribute certificate unique identifiers

SYNOPSIS
        #include <openssl/x509.h>

        void X509_get0_uids(const X509 *x, const ASN1_BIT_STRING **piuid,
                            const ASN1_BIT_STRING **psuid);

        #include <openssl/x509_acert.h>

        ASN1_BIT_STRING *X509_ACERT_get0_issuerUID(X509_ACERT *x);
       =head1 DESCRIPTION

       X509_get0_uids() sets *piuid and *psuid to the issuer and subject
       unique identifiers of certificate x or NULL if the fields are not
       present.

       X509_ACERT_get0_issuerUID() returns the issuer unique identifier of the
       attribute certificate x or NULL if the field is not present.

NOTES
       The issuer and subject unique identifier fields are very rarely
       encountered in practice outside test cases.

RETURN VALUES
       X509_get0_uids() does not return a value.

       X509_ACERT_get0_issuerUID() returns a unique identifier on success or
       NULL on failure.
