Field Details

acceptSelfSigned

protected final boolean acceptSelfSigned

A boolean that indicates if this trust manager will allow self-signed certificates to be trusted.

trustedIssuers

protected final Set<X509Certificate> trustedIssuers

The set of trusted issuers from the trust store. Note that these certificates are not validated. It is assumed that this set can be long-lived. Time-based validation should occur close to the actual usage / invocation.

Determine if the given partial or complete certificate chain can be trusted to represent the entity that is defined by the criteria specified by the 'selector' argument. A (valid) partial chain is a chain that, combined with certificates from the trust store in this manager, can be completed to a full chain. Chains provided to this method do not need to be in any particular order. This implementation uses the trust anchors as represented by getAcceptedIssuers() to verify that the chain that is provided either includes a certificate from an accepted issuer, or is directly issued by one. Depending on the configuration of this class, other verification is done:

• acceptSelfSigned: when true, any chain that has a length of one and is self-signed is considered as a 'trust anchor' (but is still subject to other checks, such as expiration checks).

This method will either return a value, which indicates that the chain is trusted, or will throw an exception.

Parameters:

selector - Characteristics of the entity to be represented by the chain (cannot be null).

chain - The certificate chain that is to be verified (cannot be null or empty).

Returns:

A trusted certificate path (never null).

Throws:

InvalidAlgorithmParameterException - if the algorithm is invalid

NoSuchAlgorithmException - if the algorithm could not be found

CertPathBuilderException - if there was a problem with the certificate path
