Value representing the different verification flags used to verify an FTP server's certificate. Note: This enumeration is not available in Xceed FTP for .NET Compact Framework because this product does not support Secure FTP.
All flags pertaining to verification are included.
AllowUnknownCA
16
Ignore that the chain cannot be verified due to an unknown certificate authority (CA).
IgnoreCARevUnknown
1024
Ignore that the certificate authority revocation is unknown when determining certificate verification.
IgnoreCtlTimeNotValid
2
Ignore that the certificate trust list (CTL) is not valid, for reasons such as the CTL has expired, when determining certificate verification.
IgnoreEndRevUnknown
256
Ignore that the end certificate (the user certificate) revocation is unknown when determining certificate verification.
IgnoreInvalidBasicConstraints
8
Ignore that the basic constraints are not valid when determining certificate verification.
IgnoreInvalidName
64
Ignore that the certificate has an invalid name when determining certificate verification.
IgnoreInvalidPolicy
128
Ignore that the certificate has invalid policy when determining certificate verification.
IgnoreRootRevUnknown
2048
Ignore that the root revocation is unknown when determining certificate verification.
IgnoreSignerRevUnknown
512
Ignore that the certificate trust list (CTL) signer revocation is unknown when determining certificate verification.
IgnoreTimeNotNested
4
Ignore that the CA (certificate authority) certificate and the issued certificate have validity periods that are not nested when verifying the certificate. For example, the CA cert can be valid from January 1 to December 1 and the issued certificate from January 2 to December 2, which would mean the validity periods are not nested.
IgnoreTimeNotValid
1
Ignore certificates in the chain that are not valid either because they have expired or they are not yet in effect when determining certificate validity.
IgnoreWrongUsage
32
Ignore that the certificate was not issued for the current use when determining certificate verification.

0
No flags. This is the most severe form of validation: No certificate anomalies will be accepted.
