Create a self-signed SSL cert for 20 years!
I was thinking, if you are making your own cert for internal use or testing, why make it for only a year?
Here’s how to make one that won’t expire for twenty years…
Generate a key:
openssl genrsa -des3 -out test.key 1024
Remove the passphrase:
cp test.key test.key.orig
openssl rsa -in test.key.orig -out test.key
Create the CSR:
openssl req -new -key test.key -out test.csr
Create the 20 year cert:
openssl x509 -req -days 7305 -in test.csr -signkey test.key -out test.crt
