#include <openssl/x509.h> int X509_verify(X509 *x, EVP_PKEY *pkey); int X509_self_signed(X509 *cert, int verify_signature); int X509_REQ_verify_ex(X509_REQ *a, EVP_PKEY *pkey, OSSL_LIB_CTX *libctx, const char *propq); int X509_REQ_verify(X509_REQ *a, EVP_PKEY *r); int X509_CRL_verify(X509_CRL *a, EVP_PKEY *r);
X509_self_signed() checks whether certificate cert is self-signed. For success the issuer and subject names must match, the components of the authority key identifier (if present) must match the subject key identifier etc. The signature itself is actually verified only if verify_signature is 1, as for explicitly trusted certificates this verification is not worth the effort.
X509_REQ_verify_ex(), X509_REQ_verify() and X509_CRL_verify() verify the signatures of certificate requests and CRLs, respectively.
X509_self_signed() returns the same values but also returns 1 if all respective fields match and verify_signature is 0.
X509_REQ_verify_ex(), and X509_self_signed() were added in OpenSSL 3.0.
