Should I upgrade the version installed with OS X Yosemite?
You should definitely not upgrade the system provided version of OpenSSL, because it can break all applications depending on the exact version provided (ABI included). I don't know what you mean by user (the command line tool or the library), but if you need an updated version of OpenSSL (or...
Client Certificate Authentication and User Enrollment

The user authentication feature is it's own separate security realm. It allows you to specify a dependent user auth realm that is used when an x509 certificate is not provided by the client. The dependent realm is basically used to enroll the device/user/app into your PKI. The dependent realm can...

Use Client Cert and TLS_RSA_WITH_AES_256_CBC_SHA256 cipher suite
According to openssl, this is also called "AES256-SHA256". According to Ruby lang, AES256-SHA256 is considered insecure and therefor disabled. The link contains a "patch" to re-enable the insecure ciphers. You may want to seek advise from a security pro about the risks involved for your organisation. (Edit) The error "self...
Ruby OpenSSL AES-128-CTR
No, you're not missing something small, you are missing something huge. Instead of using the same IV as used for encryption, you are generating a new one. For CTR, if the IV is random then each counter value is different, resulting in random looking output. Often the IV (or nonce...
Decrypt the content of a signed CMS_ContentInfo*
I have found my solution. Here is the piece of code I have used : BIO* output = BIO_new(BIO_s_mem()); if (CMS_verify(cms, stack, store, dcont, nullptr, CMS_NOINTERN)) { CMS_ContentInfo* cms2 = SMIME_read_CMS(dcont, nullptr); } Apparently, it is the dcont BIO that holds the SignedData and I can properly decrypt it afterwards...
How to increment the value of an unsigned char * (C)
I am assuming your pointer refers to 20 bytes, for the 160 bit value. (An alternative may be text characters representing hex values for the same 160 bit meaning, but occupying more characters) You can declare a class for the data, and implement a method to increment the low order...
get Subject Key Identifier of certificate with openssl commands [closed]
linux,mono,openssl,certificate
Since you mentioned you need to find X.509 extensions via command line: openssl x509 -in cert.pem -noout -text You should see that extensions are printed as shown here: X509v3 extensions: X509v3 Basic Constraints: CA:TRUE X509v3 Key Usage: Certificate Sign, CRL Sign Netscape Comment: OpenSSL Generated Certificate X509v3 Subject Key Identifier:...
How to do two-way authentication on tomcat?
tomcat,openssl,client-certificates,self-signed,mutual-authentication
I could able to identify solution after many days of search. Steps below explains, two-way authentication using openssl self signed certificate on tomcat. Server Key Generation: generate server private key : `openssl ecparam -name prime256v1 -out serverKey.pem -genkey` generate the self-signed certificate for the server, `openssl req -new -x509 -key...
Get RSA keys in a “simple” form
This is the simple form - including the header and footer and extra newlines. Most certificate programs can handle this form just fine.
Segmentation fault with generating an RSA and saving in ASN.1/DER?
pub_l = malloc(sizeof(pub_l)); is simply not needed. Nor is priv_l = malloc(sizeof(priv_l));. Remove them both from your function. You should be populating your out-parameters; instead you're throwing out the caller's provided addresses to populate and (a) populating your own, then (b) leaking the memory you just allocated. The result is...
Open Pegasus 2.14.1 client connection issue
I got response from Open Pegasus dev team. They created bug for the issue with "magic" constant. Also they recommending in my case to use sslBackwardCompatibility = true configuration for the build. This setting helped me partially. For some Storage Arrays the SSL communication started work. But for some it...
Subject Alternative Name not present in certificate
You can use: copy_extensions = copy under your CA_default section in your openssl.cnf. but only when you're sure that you can trust the extensions in the CSR as pointed out in this thread: http://openssl.6102.n7.nabble.com/subjectAltName-removed-from-CSR-when-signing-td26928.html See also: How can I generate a self-signed certificate with SubjectAltName using OpenSSL?...
Can't set public/private key in OpenSSL
The private key you're passing is invalid; it's missing newlines. There needs to be one right after the -----BEGIN PRIVATE KEY----- header, another one before the corresponding footer, and one after every 64 characters in the body, e.g. std::string privateKey = "-----BEGIN RSA PRIVATE KEY-----\n" "MIIEogIBAAKCAQEAris+hDVFJ4l1PQnpToA+qE5ZpMT1maGngVFVy8JYdmhOALP/\n" "ETGiKU7MavTPFJmOy+vRlR6OdfsJgAq1tX7RGt0ua1S0bjq8BTWBi1Ja244uIbg+\n" /* ... */...
