CATool is an opinionated command line utility which simplifies the creation of a self-signed certificate
authority and self-signed certificates.
CATool supports both RSA 4096 bit and Elliptic Curve ECDSA with curve P256.
In addition it uses SHA-2 hashing algorithms.
Finally CATool allows to pass additional common names and ip addresses via the command flags.
Build: go build
Cross compile for Linux (in case you are in MacOS): env GOOS=linux GOARCH=amd64 GOARM=7 go build
This tool automatically overwrite the files for the certificate authority and certificates in general, without asking!
There are two main commands:
./catool ca./catool cert
When executed they print additional possible command line flags.
The first one is used to create a certificate authority.
The second one to sign a certificate from the previously generated certificate authority.
- Create a certificate authority
catool ca -rsa=true -org "Sec51 Root CA" -years 1 -common-names ca.sec51.com
- Create and sign a certificate
# From the same directory where the CA certificate and private keys are located
catool cert -rsa=true -org "Sec51 Root CA" -years 1 -name server1.sec51.com -common-names server1,server1.dc1 -ip 127.0.0.1
- Create a certificate authority
catool ca -org "Sec51 Root CA" -years 1 -common-names ca.sec51.com
- Create and sign a certificate
# From the same directory where the CA certificate and private keys are located
catool cert -org "Sec51 Root CA" -years 1 -name server1.sec51.com -common-names server1,server1.dc1 -ip 127.0.0.1
