Manual page for OpenSSL ec command states:
The PEM private key format uses the header and footer lines:
—–BEGIN EC PRIVATE KEY—–
—–END EC PRIVATE KEY—–
The PEM public key format uses the header and footer lines… Continue reading Why PEM encodings of EC public and private keys use different headers?
So I come from windows background and new to SSh. We are in Linux environment now and as much as I like SSh and see its benefits, what I have realized is that it can be implemented in different ways. Now, for the longest time… Continue reading Why to use .PEM file in ssh process
I use certbot to generate ssl cert for my domain.
Then I use the following commands to copy the content to clipboard
cat ./letsencrypt/live/mycompany.com/cert.pem |pbcopy
cat ./letsencrypt/live/mycompany.com/privkey.pem |pb… Continue reading How to convert a certbot certificate private key to "Unencrypted PEM encoded RSA"?
I hope my question is not too general, but I find the topic of storing asymmetric keys very confusing..
Here’s how I understand it:
Using openSSL I can generate my RSA keys pair:
openssl genrsa -out private.pem gives me a … Continue reading PEM, CER, CRT, P12 – what is it all about?
When base64 encoding a certificate in PEM format (for transprting it within XML), the content is first converted to binary and then base64 encoded. Are there any other options? E.g. do I have to specify a character set or is … Continue reading Base64 encoding PEM
I know the pem keys are enclosed within ‘—–BEGIN RSA PUBLIC KEY—–‘ and ‘—–END RSA PUBLIC KEY—–‘. At the high level how is the format of the key itself inside this enclosure defined?

I’d like to create a self signed certificate with extensions using Key Store Explorer (KSE) but i’m not sure how to achieve this. When I do it via openssh i use the following procedure:
edit openssl.cnf
[ v3_ca ]

I manage a system that stores RSA private keys.
The user can insert the keys either encrypted or clear text (it’s always PEM though). the user also insert a passphrase.
using the openSSL API (and not CLI), I have two questio… Continue reading How To decrypt a private key stored in PEM format file
pemcracker is a tool for cracking PEM files that are encrypted and have a password. The purpose is to attempt to recover the password for encrypted PEM files while utilising all the CPU cores. Inspired by Robert Graham’s pemcrack, it still uses high-level OpenSSL calls in order to guess the password. As an optimisation, instead […]
