- Check an SSL connection: - Generate a 2048bit RSA private key and save it to a file:
`openssl s_client -connect {{domain}}:{{port}}` `openssl genrsa -out {{filename.key}} 2048`
- Generate new private key and CSR: - Generate a certificate signing request to be sent to a certificate authority:
`openssl req -out {{path/to/CSR.csr}} -new -newkey rsa:2048 -nodes -keyout {{path/to/pivate.key}}` `openssl req -new -sha256 -key {{filename.key}} -out {{filename.csr}}`
- Read contents of a certificate: - Generate a self-signed certificate from a certificate signing request valid for some number of days:
`openssl x509 -text -noout -in {{path/to/certificate.crt}}` `openssl x509 -req -days {{days}} -in {{filename.csr}} -signkey {{filename.key}} -out {{filename.crt}}`
- Read contents of a private key: - Display the certificate presented by an SSL/TLS server:
`openssl rsa -check -in {{path/to/pivate.key}}` `openssl s_client -connect {{host}}:{{port}} </dev/null`
- Verify a CSR file: - Display the complete certificate chain of an HTTPS server:
`openssl req -text -noout -verify -in {{path/to/CSR.csr}}` `openssl s_client -connect {{host}}:443 -showcerts </dev/null`
- Check MD5 hash of a certificate:
`openssl x509 -noout -modulus -in {{path/to/certificate.crt}} | openssl md5`
- Check MD5 hash of a private key:
`openssl rsa -noout -modulus -in {{path/to/pivate.key}} | openssl md5`
- Check MD5 hash of a CSR file:
`openssl req -noout -modulus -in {{path/to/CSR.csr}} | openssl md5`
