1 android.patch: 2 3 patch against Bouncy Castle: 4 5 The main differences involve removing algorithms not included in the 6 reference implementation (RI). The libcore 7 java.security.StandardNames test support class provides the most 8 up-do-date documentation of differences between the RI's list of 9 supported algorithms and Android's. Some notable omissions versus the 10 RI: 11 - LDAP 12 - MD2 13 - RC2 14 15 Other 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 - DERPrintableString interns its internal String values 20 - DERObjectIdentifier interns its internal String indentifer value 21 - changed uses of 'new Integer' to 'Integer.valueOf' 22 - X509CertificateObject.getEncoded caches its result 23 - removed references to SecretKeyFactory.PBE/PKCS5 SecretKeyFactory.PBE/PKCS12 24 - OpenSSLDigest uses NativeCrypto JNI API 25 - KeyStoreSpis made more tolerant of non-existant and null aliases 26 - PKCS12 KeyStore.getCreationDate tries to mimic RI behavior on null and missing aliases 27 - Make PKCS12 KeyStore throw error when setting non-PrivateKey, instead of on get 28 - Make PKCS12 KeyStore tolerate setting with an empty certificate chain 29 - Fixed cut & paste instanceof error in EncryptedPrivateKeyInfo 30 - Make BouncyCastleProvider.PROVIDER_NAME final 31 - Added wrapper for SecretKeyFactory.PBKDF2WithHmacSHA1 32 - Added DSA support to JDKKeyManager.engineGetKeySpec 33 34 Other security changes: 35 - Blacklist fraudulent Comodo certificates in PKIXCertPathValidatorSpi 36 - Blacklist compromised DigiNotar Root CA by public key to block cross-signed intermediates 37 38 Other changes: 39 - Log entry and exit to DHParametersHelper.generateSafePrimes which has long, unpredictable runtime 40
