2
3patch against Bouncy Castle's bcprov:
4
5The main differences involve removing algorithms not included in the
6reference implementation (RI). The libcore
7java.security.StandardNames test support class provides the most
8up-do-date documentation of differences between the RI's list of
9supported algorithms and Android's. Some notable omissions versus the
10RI:
11- LDAP
12- MD2
13- RC2
14
15Other performance (both speed and memory) and correctness changes:
16- singleton DERNull (BouncyCastle now does this but we make constructor private to be sure)
17- similarly made DERBoolean constructor private and moved to DERBoolean.{getInstance,TRUE,FALSE}
18- removed use of Boolean constructor
19- DERObjectIdentifier interns its internal String indentifer value
20- changed uses of 'new Integer' to 'Integer.valueOf'
21- X509CertificateObject.getEncoded caches its result
22- removed references to SecretKeyFactory.PBE/PKCS5 SecretKeyFactory.PBE/PKCS12
23- OpenSSLDigest uses NativeCrypto JNI API
24- KeyStoreSpis made more tolerant of non-existant and null aliases
25- PKCS12 KeyStore.getCreationDate tries to mimic RI behavior on null and missing aliases
26- Make PKCS12 KeyStore throw error when setting non-PrivateKey, instead of on get
27- Make PKCS12 KeyStore tolerate setting with an empty certificate chain
28- Fixed cut & paste instanceof error in EncryptedPrivateKeyInfo
29- Make BouncyCastleProvider.PROVIDER_NAME final
30- Added wrapper for SecretKeyFactory.PBKDF2WithHmacSHA1
31- Fixed BaseKeyFactorySpi to convert all Exceptions to InvalidKeySpecException for KeyRepTest
32
33Other security changes:
34- Blacklist fraudulent Comodo certificates in PKIXCertPathValidatorSpi
35- Blacklist compromised DigiNotar Root CA by public key to block cross-signed intermediates
36
37Other changes:
38- Log entry and exit to DHParametersHelper.generateSafePrimes which has long, unpredictable runtime

42
43patch against Bouncy Castle's bcpkix:
44
45The main differences involve:
46- removing algorithms not in our bcprov (MD2, MD4, SHA224, RIPEMD, GOST)
47- using the singleton DERNull.INSTANCE
