NF

All methods for managing PKCS#7 SignedData objects will be available.

BOOLEAN

B

Constructor BOOLEAN(boolean) ignored the boolean value.

RSAPrivateKey

B

Coefficient calculation was not according to PKCS#1.

This X.509v3 extension now also handles policy qualifiers

SSLRSASignature

NF

RSA Signature as defined in SSL v3.0 protocol (uses MD5 and SHA hash)

NumericString

Description and Examples

All Packages

C

To be more flexible for future enhancements the package structure has been reorganized.
List of changes:

• iaik.security.pkcs -> iaik.pkcs
• iaik.security.x509 -> iaik.x509
• iaik.security.interfaces -> iaik.interfaces
• iaik.security.provider -> iaik.security.cipher
• iaik.security.provider -> iaik.security.rsa

PKCS12

NF

First application for PKCS#12. The class can now be used to parse PKCS#12 objects  exported by Microsoft Internet Exoplorer. The files contain the certificate chain and the private key of the user.

Example:
PKCS12 pkcs12 = new PKCS12("file.export"); System.out.println(pkcs12); // the password used when exporting pkcs12.decrypt("password"); System.out.println(pkcs12); RSAPrivateKey pk = pkcs12.getPrivateKey(); X509Certificate[] certList = pkcs12.getCertificateList();

PKCS7

NF

First application for PKCS#7. The class can now be used to parse and create certificate chains as used by Netscape Navigator and Microsoft Internet Explorer (extension .p7c).

Example:
X509Certificate[] certs = ...; PKCS7 pkcs7 = new PKCS7(); pkcs7.createCertificateList(certs); pkcs7.setFormat(ASN1.DER); pkcs7.saveToFile(pkcs7File); or: PKCS7 pkcs7 = new PKCS7("certs.p7c"); X509Certificate[] certs = pkcs7.getCertificateList();

iaik.asn1

C

Complete reorganisation of this package. ASN.create is no longer needed:
More examples can be found in: demo/iaik-jce/TestASN1.java

Example:
SEQUENCE seq = new SEQUENCE(); seq.addComponent(new INTEGER(1234));

all packages

C

Harmonisation of the API

Example:
obj.setFormat (ASN1.DER); obj.toByteArray(); // DER encoded obj.saveToFile(); // DER encoded

Base64 OutputStream

B

Base64 encoding was wrong when length of array to encode > 1024

SET

B

SET with indefinite length = 0 caused an CodingException

SEQUENCE

B

SEQUENCE with indefinite length = 0 caused an CodingException

RSAPrivateKey

NF

New constructor which only needs modulus, public exponent and private exponent.

NF

New method: getPublicExponent();

IAIK-JCE 1.2beta: 24. September 1997

Description and Examples

CFBMode

NF

n-Bit CFB (n must be a multiple of 8)

Example:
Cipher c = Cipher.getInstance ("DES.CFB8");...byte[] in = {44};byte[] out = c.crypt(in);

OFBMode

NF

n-Bit OFB (n must be a multiple of 8)

Example:
Cipher c = Cipher.getInstance ("DES.OFB8");...byte[] in = {44};byte[] out = c.crypt(in);

CRL

B

Revoked certificates were not OPTIONAL in CRLs.

CipherOutput Stream

B

Method flush() now also flushes the underlying output stream.

Cipher

C

Method setCipherMode(..) doesn't throw an InvalidParameterException anymore.

C

Method setInitializationVector(..) now throws a InvalidAlgorithmParameterException if the IV has a wrong length.

NF

Now it is possible to use a n-Bit CFB and a n-Bit OFB. You get this new feature over Cipher.getInstance("DES.CFB8"); allowed values: CFB = CFB64, CFB8, CFB16, ..., CFB[blocklength*8]

B

Padding length calculation was wrong.

Idea

B

Internal key generation bug.

MD5RSASignature

C

DigestAlgorithmID is now AlgorithmID.md5 instead of AlgorithmID.md5 With RSAEncryption.

ShaRSASignature

C

DigestAlgorithmID is now AlgorithmID.sha instead of AlgorithmID.sha With RSAEncryption.

RSAPrivateKey

B

Ensure that

otherwise fast en/decryption will not work.

ChoiceOfTime

B

Year for UTCTime was wrong.

RSAKey

B

If first bit in a signature was get, a negative BigInteger was created.
