Useful OpenSSL Commands
Get ssl cert expiration date
openssl s_client -connect secure.healthcareerweb.com:443 2>/dev/null </dev/null | openssl x509 -noout -enddate
Ensure key and crt match
- The following should be the same md5 sum if the key and crt match.
openssl x509 -noout -modulus -in server.pem | openssl md5 ; openssl rsa -noout -modulus -in server.key | openssl md5
Remove passphrase from private key
openssl.exe rsa -in privateKey.pem -out private.pem
Generate key with password
openssl genrsa -des3 -out www.domain.com.key 2048
Generate key & csr without password
openssl req -nodes -newkey rsa:2048 -keyout domain.com.key -out domain.com.csr

openssl x509 -in filename.crt -noout -text
View csr details
openssl req -noout -text -in server.csr
Using openssl instead of telnet
- openssl s_client -connect www.mysite.com:443
- ssl info scrolls by
- Now do a normal get:
GET /healthcheck.txt HTTP/1.1 \n Host: www.getauto.com
IMAP
Connect
s_client -connect mail.district65.net:993 a1 login <user> <pass>
List Folders
a1 LIST "" "*"
