IAIK-JCE 5.52 and iSaSiLk 5.2 released!


The new versions of IAIK-JCE and iSaSiLk follow up the recently released new version of IAIK-ECCelerateTM (5.0). IAIK-JCE 5.52 brings some fixes and additions, and iSaSiLk 5.2 adds support for x25519 and x448 ECDHE key exchange and EdDSA signing using Curve25519 and Curve448. Furthermore iSaSiLk now supports RSA-PSS signatures.

ECCelerate 5.0 released!


We proudly present a new maintenance release of our IAIK ECCelerate™ elliptic curve library! Version 5.0 adds support EdDSA using Curve25519 and Curve448, ECDH using X25519 and X448, and RFC6979. IAIK ECCelerate™ is based on Java 6 technology and has been thoroughly optimized for speed. Currently, it supports ECDSA, EdDSA, ECDH, X25519/448, ECIES and optionally ECMQV.


Our Clients


IAIK-JCE works on any Java™ version starting with JDK 1.2 up to the most recent versions. Due to US Law Export Regulations JDK versions prior 1.4 do not contain the original Java™ JCE APIs. For that reason IAIK-JCE provides a re-implementation of the entire Java™ Cryptography Extension from SUN:

  •  package javax.crypto
  •  package javax.crypto.spec
  •  package javax.crypto.interfaces

With JDK1.4 the JCE framework (JAVAX CRYPTO) has been incorporated into the standard JDK. However, because of export regulations a JCE provider only can be used with JDK 1.4 or later if it is signed. For that reason we provide a signed version of our crypto toolkit IAIK-JCE, too.
IAIK-JCE comes with its own security provider offering a great variety of cryptographic services, algorithms and secure random number generators. The X.509 package supports X.509 public key, qualified and attributes certificates, revocation information handling via CRLs and OCSP, and searching and downloading certificates or CRLs from LDAP directories.. Comprehensive ASN.1 and PKCS APIs allow easy modelling of ASN.1 structures, secure storing of sensitive keying and data material, and signing or encrypting digital documents. An extensive demo source library makes it easy to soon become familiar with Cryptography for the Java™ platform and IAIK-JCE.

Since IAIK-JCE version 5.0 we have been delivering an optional AES addon, which makes use of the AES-NI instruction set extensions of modern x86 CPUs. Using this addon the throughput of AES can be sped up tremendously. Take a look at our speed tables to see the difference.

The IAIK provider

The provider architecture has been introduced by the Java™ Cryptographic Architecture (JCA), making it possible for different cryptographic implementations to operate on common interfaces (consult the Java™ Cryptography Architecture API Specification & Reference).

The term provider is an abbreviation for Cryptographic Package Provider and denotes a package or a set of packages supplying concrete implementations of some cryptographic services of the Java™ Cryptography API (see JCA). A JCA provider may realise implementations of digital signature, message digest and key pair generation algorithms, certificate factories and keystores. If the JCA API is extended by the Java™ Cryptography Extension (JCE) API, a provider may also implement encryption, message authentication and key exchange algorithms.

The master class of the IAIK security package provider is class IAIK of package It extends class for registering the IAIK provider specific cryptographic implementations within the Java™ cryptography architecture. The IAIK provider supports both, algorithm implemetations for JCA and for the JCE extension (see below).
