MailSecurityInfo Type

Contains security details for the processed e-mail message.

Remarks

This object provides access to security details of an e-mail message.

Fields

chainValidationDetails
Int32

The details of a certificate chain validation outcome. They may often suggest what reasons that contributed to the overall validation result.

Returns a bit mask of the following options:

cvrBadData0x0001One or more certificates in the validation path are malformed

cvrRevoked0x0002One or more certificates are revoked

cvrNotYetValid0x0004One or more certificates are not yet valid

cvrExpired0x0008One or more certificates are expired

cvrInvalidSignature0x0010A certificate contains a non-valid digital signature

cvrUnknownCA0x0020A CA certificate for one or more certificates has not been found (chain incomplete)

cvrCAUnauthorized0x0040One of the CA certificates are not authorized to act as CA

cvrCRLNotVerified0x0080One or more CRLs could not be verified

cvrOCSPNotVerified0x0100One or more OCSP responses could not be verified

cvrIdentityMismatch0x0200The identity protected by the certificate (a TLS endpoint or an e-mail addressee) does not match what is recorded in the certificate

cvrNoKeyUsage0x0400A mandatory key usage is not enabled in one of the chain certificates

cvrBlocked0x0800One or more certificates are blocked

cvrFailure0x1000General validation failure

cvrChainLoop0x2000Chain loop: one of the CA certificates recursively signs itself

cvrWeakAlgorithm0x4000A weak algorithm is used in one of certificates or revocation elements

cvrUserEnforced0x8000The chain was considered invalid following intervention from a user code

chainValidationResult
ChainValidities

The outcome of a certificate chain validation routine.

Available options:

cvtValid0The chain is valid

cvtValidButUntrusted1The chain is valid, but the root certificate is not trusted

cvtInvalid2The chain is not valid (some of certificates are revoked, expired, or contain an invalid signature)

cvtCantBeEstablished3The validity of the chain cannot be established because of missing or unavailable validation information (certificates, CRLs, or OCSP responses)

Use the ValidationLog property to access the detailed validation log.

claimedSigningTime
String

Returns the signature's claimed signing time.

Use this property to get the signature creation time from the signer's computer. Note that the claimed time is not covered by a trusted timestamp and may be forfeited or wrong. The time is provided in UTC.

encrypted
Bool

Indicates whether the message is encrypted.

encryptionAlgorithm
String

Indicates the algorithm that was used to encrypt the message.

hashAlgorithm
String

Specifies the hash algorithm that was used to calculate the signature.

signatureValidationResult
SignatureValidities

The outcome of the cryptographic signature validation.

The following signature validity values are supported:

svtValid0The signature is valid

svtUnknown1Signature validity is unknown

svtCorrupted2The signature is corrupted

svtSignerNotFound3Failed to acquire the signing certificate. The signature cannot be validated.

svtFailure4General failure

signed
Bool

Indicates whether the message is signed.

validationLog
String

Contains the signing certificate's chain validation log. This information may be very useful in investigating chain validation failures.

Constructors

public init()

Creates a new MailSecurityInfo object.
