.Nd insecure TLS configuration
.Sh SYNOPSIS
.In tls.h
.Ft void
.Fn tls_config_verify "struct tls_config *config"
.Ft void
.Fn tls_config_insecure_noverifycert "struct tls_config *config"

.Sh DESCRIPTION
These functions disable parts of the normal certificate verification
process, resulting in insecure configurations.
Be very careful when using them.
.Pp
.Fn tls_config_insecure_noverifycert
disables certificate verification and OCSP validation.
.Pp
.Fn tls_config_insecure_noverifyname
disables server name verification (client only).
.Pp
.Fn tls_config_insecure_noverifytime
disables validity checking of certificates and OCSP validation.
.Pp
.Fn tls_config_verify
reenables server name and certificate verification.
