Constructor Detail

PreferredSignatureAlgorithms.PreferredSignatureAlgorithm

public PreferredSignatureAlgorithms.PreferredSignatureAlgorithm(AlgorithmID sigIdentifier)

Creates a PreferredSignatureAlgorithm with the given signature algorithm identifier.

Parameters:

sigIdentifier - the signature algorithm identifier (will not be cloned)

PreferredSignatureAlgorithms.PreferredSignatureAlgorithm

public PreferredSignatureAlgorithms.PreferredSignatureAlgorithm(ASN1Object asn1Obj)
                                                         throws CodingException

Creates a PreferredSignatureAlgorithm from its ASN.1 representation.

Parameters:

asn1Obj - the ASN.1 representation of the PreferredSignatureAlgorithm

Throws:

CodingException - if the ASN1Object could not be parsed

Method Detail

setPubKeyAlgIdentifier

public void setPubKeyAlgIdentifier(SMIMECapability pubKeyAlgIdentifier)

Sets the public key algorithm identifier the client prefers in the responder certificate.

Parameters:

pubKeyAlgIdentifier - the public key algorithm identifier

getPubKeyAlgIdentifier

public SMIMECapability getPubKeyAlgIdentifier()

Gets the public key algorithm identifier the client prefers in the responder certificate.

Returns:

the public key algorithm identifier or null if no public key algorithm identifier is included

getSigIdentifier

public AlgorithmID getSigIdentifier()

Gets the signature algorithm identifier the client prefers.

Returns:

the signature algorithm identifier

decode

public void decode(ASN1Object asn1Obj)
            throws CodingException

Decodes this PreferredSignatureAlgorithm from its ASN.1 representation.

A PreferredSignatureAlgorithm specifies the preferred signature algorithm and (optionally) the public key algorithm identifier the client prefers in the responder certificate:

 PreferredSignatureAlgorithm ::= SEQUENCE {
    sigIdentifier        AlgorithmIdentifier,
    pubKeyAlgIdentifier  SMIMECapability OPTIONAL
    }

 

Parameters:

asn1Obj - the ASN.1 representation of the PreferredSignatureAlgorithm

Throws:

CodingException - if the ASN1Object could not be parsed

toASN1Object

public ASN1Object toASN1Object()
                        throws CodingException

Returns this PreferredSignatureAlgorithm as ASN.1 object.

A PreferredSignatureAlgorithm specifies the preferred signature algorithm and (optionally) the public key algorithm identifier the client prefers in the responder certificate:

 PreferredSignatureAlgorithm ::= SEQUENCE {
    sigIdentifier        AlgorithmIdentifier,
    pubKeyAlgIdentifier  SMIMECapability OPTIONAL
    }

 

Returns:

the ASN.1 representation of the PreferredSignatureAlgorithm

Throws:

CodingException - if the ASN1Object cannot be created

hashCode

public int hashCode()

Returns a hash code for this PreferredSignatureAlgorithm.

The hash code is calculated from the signature algorithm identifier only.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code for this PreferredSignatureAlgorithm

equals

public boolean equals(java.lang.Object obj)

Compares this PreferredSignatureAlgorithm to the specified object.
The comparison is based on the encoding, i.e. any parameters are included in the comparison and NULL and absent parameters will give a negative comparison result.

Overrides:

equals in class java.lang.Object

Parameters:

obj - the object to compare this PreferredSignatureAlgorithm against.

Returns:

true, if the given object is equal to this PreferredSignatureAlgorithm, false otherwise

toString

public java.lang.String toString()

Gets a String representation of this object.

Overrides:

toString in class java.lang.Object

Returns:

the string representation
