java.security.spec Documentation Differences

This file contains all the changes in documentation in the package java.security.spec as colored differences. Deletions are shown like this, and additions are shown like this.

If no deletions or additions are shown in an entry, the HTML tags will be what has changed. The new HTML tags are shown in the differences. If no documentation existed, and then some was added in a later version, this change is noted in the appropriate class pages of differences, but the change is not shown on this page. Only changes in existing text are shown here. Similarly, documentation which was inherited from another class or interface is not shown here.

Note that an HTML error in the new documentation may cause the display of other documentation changes to be presented incorrectly. For instance, failure to close a <code> tag will cause all subsequent paragraphs to be displayed differently.

A (transparent) specification of cryptographic parameters.

This interface contains no methods or constants. Its only purpose is to group (and provide type safety for) all parameter specifications. All parameter specifications must implement this interface. @author Jan Luehe @version 1.7 9811 02/1202/0300 @see java.security.AlgorithmParameters @see DSAParameterSpec @since JDK11.2

A (transparent) specification of the key material that constitutes a cryptographic key.

If the key is stored on a hardware device its specification may contain information that helps identify the key on the device.

A key may be specified in an algorithm-specific way or in an algorithm-independent encoding format (such as ASN.1). For example a DSA private key may be specified by its components x p q and g (see o it may be specified using its DER encoding (see This interface contains no methods or constants. Its only purpose is to group (and provide type safety for) all key specifications.
