问题 I am attempting to install the expo package from npm, but during the install process, I receive an error, error:0906D06C:PEM routines:PEM_read_bio:no start line , multiple times as it tries to fetch .tar.gz files, and then the installation fails. I looked around, but all I have been able to find is examples of that error when people were setting up their own servers and had issues with their certs. But I'm not trying to set up a server, I'm trying to download a package, I don't have any certs

问题 I am trying to get client Samsung tablet to work with site requiring client devices to have cert. I can get it working on tablets with 5.0+ because webview has onReceivedClientCertRequest. So I can use that to then load the cert and the key. But I am having problems on tablets running 4.4.2 because that onReceivedClientCertRequest function is for 5+. When I run on 4.4.2 my concern is that the logger shows: '12-23 12:46:07.541 20804-20804/com.example.ssltest I/chromium: [INFO:aw_content

问题 Can a particular web page in a web site, authonticate a web request using client side SSL certificate, while others don't? 回答1: It's possible using SSL/TLS renegotiation. The way to configure it depends on the server you're using (and whether it supports it). Note that, at the end of last year (October/November 2009), an SSL/TLS protocol flaw was discovered regarding this feature. SSL/TLS stacks that support renegotiation based on code before that will be vulnerable to the attack. Most

问题 I am using following code (simplified little bit) to get certificate string from X509 structure. Basically PEM_write_bio_X509 function. X509 *certificate... .... BIO *bio = BIO_new(BIO_s_mem()), BIO_vfree); if (!bio || !PEM_write_bio_X509(bio, certificate)) { // error handling } size_t keylen = BIO_pending(bio); unique_ptr<char[]> key(new char[keylen]); int len = BIO_read(bio, key.get(), (int)keylen); if (len <= 0) { // error handling } string result = string(key.get(), len); The result is

问题 I am using bouncy castle librarires to add extensions to my X509V3Certificate certificate.Let's say that I want to add ExtendedKeyUsage extension to my certificate.I am using X509V3CertificateBuilder class and addExtension() method so I do this. X509V3CertificateBuilder cf=...; ExtendedKeyUsage eku = new ExtendedKeyUsage(KeyPurposeId.anyExtendedKeyUsage); cf.addExtension(Extension.ExtendedKeyUsage, false , eku); But what I am seeing in some examples all over the web , people are doing next

问题 I have written a TLS code which is doing mutual authentication at Java, so client is sending its certificate after server sends its certificate. I would like to validate all the certificates in certificate chain by OCSP which is coming from client side to server side. I have written my loop logic as assuming that last certificate is root(CA) certificate in the chain and not to send any OCSP query for it; int certificateChainSize= x509Certificates.length; // Verifies certificate chain

问题 I have a List of Byte arrays (representing each certificate from a chain), in PEM format, and I would like to know if there's a way to convert these to a unique PKCS7 formatted String, in Java. Thank you in advance. 回答1: This is an example to build a PKCS#7 file using a X509Certificate[] array based on this answer. It does not require the private key //Export a certificate list to PKCS#7 public static byte[] exportCertificatesAsPkcs7(X509Certificate certs[]) throws Exception { List certList =
