Please help me understand and solve this problem.
Assumptions
Let’s start with an IoT design. When it is working correctly, a remote device has a pem certificate which is used to validate traffic to and from the server, which has holds th… Continue reading Is it possible to extend the validity of a pem certificate
Type 1 diabetes remains a problem despite having an apparently simple solution: since T1D patients have lost the cells that produce insulin, it should be possible to transplant those cells …read more Continue reading Implant Fights Diabetes by Making Insulin and Oxygen
I’m trying to decrypt an encrypted ECDSA_secp256k1 private key generated using the OpenSSL CLI command openssl ecparam -genkey -name secp256k1 | openssl ec -aes-128-cbc -out ecdsa_priv.pem but I want to do it using pure Javascript. I tried… Continue reading How to decrypt ECDSA_secp256k1 private key from PEM format generated with OpenSSL
I have a PCKS#8 RSA Key encrypted with a passphrase and would like to retrieve the iteration count used for the PBKDF2 used to derive the AES Key used for encryption, in order to make sure that they conform to the standard https://www.rfc-… Continue reading OpenSSL get PKCS#8 encrypted rsa PBKDF2 iteration count
I was doing some security checks in some devices in my local network and I noticed that I obtain two different certificate chains for the same domain (www.google.com) from two different devices (smartphone and desktop pc, again both connec… Continue reading Same domain, same local network, different certificate chain
Edit 2022-09-06: There is not enough information present to solve the problem as stated. Reverse engineering from the present state of the server is not going to work. I’m going to redo the cert from the ground up.
The client pem would … Continue reading Can I create a client .pem file from the CA cert, a (private key?) .pem file, and SSL .cnf file? [closed]
I have the following private key. I’d like to be able to process it into an instance of ECPrivateKey using Bouncycastle (or the builtin Java security API if bouncycastle isn’t necessary).
—–BEGIN EC PRIVATE KEY—–

Say I have an RSA private key, if encoded in PEM, it usually looks like:
—–BEGIN RSA PRIVATE KEY—–
<base64 encoded bits>
—–END RSA PRIVATE KEY—–
If I encrypt the said key with a passphrase using AES, and then encode it i… Continue reading How to properly encode in PEM an RSA private key encrypted with another RSA key?
I have a SAML offering for my clients to access my cloud based application. Should I have a portal for them to upload their certificates or should I go the easy route and just have them e-mail them to me? What would be the best practice fo… Continue reading Is it inappropriate at all for someone in my client organization to email their PEM file to me?
I am connecting to a fedora xrdp server from the built-in Windows Remote Desktop client.
I have access to the /etc/xrdp/key.pem and to the certificate inspection window on on Windows Remote Desktop
In this case I am connecting to a local … Continue reading How can I check the validity of a selfsigned xrdp certificate
