| |
| patch against Bouncy Castle: |
| |
| The main differences involve removing algorithms not included in the |
| reference implementation (RI). The libcore |
| java.security.StandardNames test support class provides the most |
| up-do-date documentation of differences between the RI's list of |
| supported algorithms and Android's. Some notable omissions versus the |
| RI: |
| - LDAP |
| - MD2 |
| - RC2 |
| |
| Other performance (both speed and memory) changes: |
| - singleton DERNull (BouncyCastle now does this but we make constructor private to be sure) |
| - similarly made DERBoolean constructor private and moved to DERBoolean.{getInstance,TRUE,FALSE} |
| - DERPrintableString interns its internal String values |
| - DERObjectIdentifier interns its internal String indentifer value |
| - changed uses of 'new Integer' to 'Integer.valueOf' |
| - Added X509NameElementList to reduce small Vector allocation for X509Name key/value operations |
| - Replaced X509Extensions hash/vector with new OrderedTable instance to cut down on memory allocation |
| - PKCS12BagAttributeCarrier also uses OrderedTable to cut down on memory allocation |
| - X509CertificateObject.getEncoded caches its result |
| - Added IndexedPKIXParameters for faster cert lookup in CertPathValidatorUtilities.findTrustAnchor |
| - CertPathValidatorUtilities.findTrustAnchor fast path compares encoded certs similar to PKIXCertPathValidatorSpi |
| - Added ASN1Collection for use as new parent for ASN1Collection and ASN1Set to reduce small Vector allocation |
| - removed references to SecretKeyFactory.PBE/PKCS5 SecretKeyFactory.PBE/PKCS12 |
| - OpenSSLDigest uses NativeCrypto JNI API |
| - KeyStoreSpis made more tolerant of non-existant and null aliases |
| - PKCS12 KeyStore.getCreationDate tries to mimic RI behavior on null and missing aliases |
| - Make PKCS12 KeyStore throw error when setting non-PrivateKey, instead of on get |
| - Make PKCS12 KeyStore tolerate setting with an empty certificate chain |
| - Added wrapper for SecretKeyFactory.PBKDF2WithHmacSHA1 |
| |
| Other security changes: |
| - blacklist fraudulent Comodo certificates in PKIXCertPathValidatorSpi |
| - blacklist compromised DigiNotar Root CA by public key to block cross-signed intermediates |
