I have a SSL/TLS client program using OpenSSL in C++ programming language. I am looking for methods to validate server certificate ( X509 ) returned by SSL_get_peer_certificate function call. Also, I have my own CA certificate loaded using SSL_CTX_load_verify_locations function. The CA certified the server certificate. I am able to make SSL session to my server. Now, i want to validate server certificate received during SSL handshake using my own CA. I couldn't find a way to do it in C or C++. #include <iostream> #include <string.h> #include <unistd.h> #include <sys/socket.h> #include <resolv

a question: Vendor says that for some encryption purpose uses PKCS#1 V2.1 OAEP with SHA-256... Is that even possible? I have checked and re-checked openssl and all they have is RSA public key encrypt with OAEP padding which is supposed to be PKCS#1 V2.1 with SHA1 So what can I do? How can I use SHA256 in RSA PUBLIC KEY encryption? IS it even possible? Best regards, EDITED: ANSWER HOW TO USE RSA ENCRYPTION USING OPENSSL OAEP PADDING AND SHA256 DIGEST #include "openssl/rsa.h" #include <openssl/err.h> #define RSA_F_RSA_PADDING_ADD_PKCS1_OAEP_MGF1 154 int RSA_padding_add_PKCS1_OAEP_mgf1_SHA256

Using Windows 7, JDK 6 (and 7). I'm trying to get personal certificates stored in Windows MSCAPI key store and it's basic properties (in order to use private key for signing). However some aliases are identified not having private key (isKeyEntry == false) although it acctually has one. Any suggestions how to deal with this "feature"? The P12 file with certificate (already revoked) & private key having this weird "property" can be downloaded from http://download.upce.cz/terena-public.pfx . Password is "password". KeyStore ks = KeyStore.getInstance("Windows-MY", "SunMSCAPI"); ks.load(null, null

In android there is a way of knowing if the public key from a key pair was generated inside TEE and is, therefore, hardware-backed ( https://source.android.com/security/keystore/attestation ). I cannot find a way to do that in iOS. Does anyone know if there is a way? I am not aware of a directly similar possibility, but if your app lives on a not-jailbroken device you can create keys and store them inside of the Secure Enclave of your iOS device and be sure that they are stored securely and can not be compromised. Note that you can only store 256-bit elliptic curve private keys. You can then

I am trying to use the iPhone's PKI libraries to encrypt a short string (12345678), but I keep getting the error -9809 (i.e. errSSLCrypto) whenever I try to use SecKeyEncrypt. The SecureTransport.h header file describes this error simply as "underlying cryptographic error", which wasn't very meaningful. My code is as follows: - (NSData *)encryptDataWithPublicKey:(NSString *)plainText { OSStatus result = -1; NSData *plainTextData = [plainText dataUsingEncoding:NSASCIIStringEncoding]; size_t plainTextLength = [plainTextData length]; SecTrustRef trustRef; SecTrustResultType trustResult;

使用yum update 更新的时候出现 “Couldn’t open file /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7” 这样的提示，去CentOS的官网：https://www.centos.org/keys/RPM-GPG-KEY-CentOS-7，找到 CentOS 7 Signing Key 下载到/etc/pki/rpm-gpg/下面，并改名叫RPM-GPG-KEY-CentOS-7，再次更新即可。 ———————————————— 版权声明：本文为CSDN博主「rznice」的原创文章，遵循 CC 4.0 BY-SA 版权协议，转载请附上原文出处链接及本声明。 原文链接：https://blog.csdn.net/rznice/article/details/84280832 来源： https://www.cnblogs.com/zl1991/p/11804000.html

I'm trying to configure a Tomcat server with SSL. I've generated a keypair thus: $ keytool -genkeypair -alias tomcat -keyalg RSA -keystore keys Next I generate a certificate signing request: $ keytool -certreq -keyalg RSA -alias tomcat -keystore keys -file tomcat.csr Then I copy-paste the contents of tomcat.csr into a form on Thawte's website, asking for a trial SSL certificate. In return I get two certificates delimited with -----BEGIN ... -----END , that I save under tomcat.crt and thawte.crt . (Thawte calls the second certificate a 'Thawte Test CA Root' certificate). When I try to import

Thanks 回答1: I assume that you're using the HttpListener hosting. To enable SSL / Client certifiacates, those settings are set by httpcfg. You can find some information at http://msdn.microsoft.com/en-us/library/ms733791.aspx . More specifically, you should be able to enable SSL with client certificates using httpcfg set ssl -i 0.0.0.0:8012 -h 0000000000003ed9cd0c315bbb6dc1c08da5e6 -f 3 On
