Only the signature is checked: no other checks (such as certificate +chain validity) are performed. +.PP +\&\fBX509_self_signed()\fR checks whether certificate \fIcert\fR 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 \fBverify_signature\fR is 1, as +for explicitly trusted certificates this verification is not worth the effort. +.PP +\&\fBX509_REQ_verify_ex()\fR, \fBX509_REQ_verify()\fR and \fBX509_CRL_verify()\fR +verify the signatures of certificate requests and CRLs, respectively. +.SH "RETURN VALUES" +.IX Header "RETURN VALUES" +\&\fBX509_verify()\fR, +\&\fBX509_REQ_verify_ex()\fR, \fBX509_REQ_verify()\fR and \fBX509_CRL_verify()\fR +return 1 if the signature is valid and 0 if the signature check fails. +If the signature could not be checked at all because it was ill-formed, +the certificate or the request was not complete or some other error occurred +then \-1 is returned. +.PP +\&\fBX509_self_signed()\fR returns the same values but also returns 1 +if all respective fields match and \fBverify_signature\fR is 0. +.SH "SEE ALSO" +.IX Header "SEE ALSO" +\&\fBd2i_X509\fR\|(3), +\&\fBERR_get_error\fR\|(3), +\&\fBX509_CRL_get0_by_serial\fR\|(3), +\&\fBX509_get0_signature\fR\|(3), +\&\fBX509_get_ext_d2i\fR\|(3), +\&\fBX509_get_extension_flags\fR\|(3), +\&\fBX509_get_pubkey\fR\|(3), +\&\fBX509_get_subject_name\fR\|(3), +\&\fBX509_get_version\fR\|(3), +\&\fBX509_NAME_ENTRY_get_object\fR\|(3), +\&\fBX509_NAME_get_index_by_NID\fR\|(3), +\&\fBX509_NAME_print_ex\fR\|(3), +\&\fBX509V3_get_d2i\fR\|(3), +\&\fBX509_verify_cert\fR\|(3), +\&\fBOSSL_LIB_CTX\fR\|(3) +.SH HISTORY +.IX Header "HISTORY" +The \fBX509_verify()\fR, \fBX509_REQ_verify()\fR, and \fBX509_CRL_verify()\fR +functions are available in all versions of OpenSSL. +.PP +\&\fBX509_REQ_verify_ex()\fR, and \fBX509_self_signed()\fR were added in OpenSSL 3.0. +.SH COPYRIGHT +.IX Header "COPYRIGHT" +Copyright 2015\-2023 The OpenSSL Project Authors.
