Constructor Details

RsaPssParameters

public RsaPssParameters(AlgorithmIdentity hash,
 AlgorithmIdentity mask,
 AlgorithmIdentity maskHash,
 int saltLength,
 int trailerField)

Creates a validated exact RSA-PSS parameter tuple.

Throws:

IllegalArgumentException - if roles or numeric parameters are contradictory

Method Details

canonicalForm

public String canonicalForm()

Description copied from interface: AlgorithmIdentity.Parameters

Returns the deterministic parameter representation.

Specified by:

canonicalForm in interface AlgorithmIdentity.Parameters

Returns:

non-blank lowercase canonical component

immutableCopy

public AlgorithmIdentity.Parameters immutableCopy()

Description copied from interface: AlgorithmIdentity.Parameters

Returns an independently owned immutable copy.

Trusted extension implementations must not return mutable caller-owned state. Immutable records may return this.

Specified by:

immutableCopy in interface AlgorithmIdentity.Parameters

Returns:

immutable owned parameters

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with the compare method from their corresponding wrapper classes.

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

hash

public AlgorithmIdentity hash()

Returns the value of the hash record component.

Returns:

the value of the hash record component

mask

public AlgorithmIdentity mask()

Returns the value of the mask record component.

Returns:

the value of the mask record component

maskHash

public AlgorithmIdentity maskHash()

Returns the value of the maskHash record component.

Returns:

the value of the maskHash record component

saltLength

public int saltLength()

Returns the value of the saltLength record component.

Returns:

the value of the saltLength record component

trailerField

public int trailerField()

Returns the value of the trailerField record component.

Returns:

the value of the trailerField record component
