# Verifying Certificates, CSRs, Keys
```shell
$ openssl pkey -in keyfile.pem -pubout -outform pem | sha256sum
$ openssl x509 -in certfile.pem -pubkey -noout -outform pem | sha256sum
$ openssl req -in csrfile.csr -pubkey -noout -outform pem | sha256sum
```
All SHAs should match if they're the correct series of files.
# Removing passwords from keys
```shell
$ openssl rsa -in keyfile.pem -out new-keyfile.pem
```
