x509certificate

问题 According to RFC 2818 (section 3.1) RFC 2459 - It seems to be allowed to have a list of DNS name entries as part of SAN names and cover multiple domains: SubjectAlternativeName [ DNSName: localhost DNSName: *.i.mydomain.net DNSName: *.mydomain.net ] Using Java keytool application - it doesn't seem to allow SAN entries to have wildcards in DNS names. Does anyone know whether I can use some tricks(!) to do this? 回答1: I've run into this problem in the past and worked around it by using OpenSSL

问题 I was just curious if there is a way to get platform.pk8 and platform.x509.pem which are used to sign the rom inside the Android device. My aim is no more than developing system applications for testing and using my self-owned devices on my desired purpose. For those who are not familiar with creating system apks: signing an apk with system signature [WITHOUT ROOTING] 回答1: No. At least, not if the person building the ROM knows what they're doing. From the docs (emphasis mine): Each key comes

问题 I have been using the ssl certificate key provided by the server team in android application under raw folder.It was working fine initially. CertificateFactory cf = CertificateFactory.getInstance("X.509"); InputStream caInputMmx = new BufferedInputStream(this.getAssets().open("123.crt")); Certificate caMmx = cf.generateCertificate(caInputMmx); String keyStoreType = KeyStore.getDefaultType(); KeyStore keyStore = KeyStore.getInstance(keyStoreType); keyStore.load(null, null); keyStore

问题 I’ve already viewed these questions and their answers: "Invalid provider type specified" CryptographicException when trying to load private key of certificate How do I create client certificates for local testing of two-way authentication over SSL? Invalid provider type specified. CryptographicException And this blog that was referenced by the second question. I suspect there is a problem with the certificate issuer, but I could be wrong. Preface I’m new at authentication (you can read that

问题 I have some string, that is separated with comma. I have to add all extension that match any of GeneralName for Subject Alternative Names extension. Can somebody finish for loop for me? @Override public boolean saveKeypair(String arg0) { KeyPair keyPair = generateKeyPair(Integer.parseInt(access.getPublicKeyParameter())); PrivateKey privateKey = keyPair.getPrivate(); PublicKey publicKey = keyPair.getPublic(); X500Name name = new X500Name(access.getSubject()); BigInteger serial = new BigInteger
