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.
Note that these interfaces are intended only for key
implementations whose key material is accessible and
available. These interfaces are not intended for key
implementations whose key material resides in
inaccessible, protected storage (such as in a
hardware device).
For more developer information on how to use these
interfaces, including information on how to design
Key classes for hardware devices, please refer
to these cryptographic provider developer guides:
Package Specification
- PKCS #1: RSA Cryptography Specifications, Version 2.2 (RFC 8017)
- Federal Information Processing Standards Publication (FIPS PUB) 186:
Digital Signature Standard (DSS)
