| Package | Description | 
|---|---|
| java.security.interfaces | Provides interfaces for generating RSA (Rivest, Shamir and
 Adleman AsymmetricCipher algorithm)
 keys as defined in the RSA Laboratory Technical Note
 PKCS#1, and DSA (Digital Signature
 Algorithm) keys as defined in NIST's FIPS-186. | 
| java.security.spec | Provides classes and interfaces for key specifications and algorithm
 parameter specifications. | 
| Class and Description |
