Perform the following tasks to test OpenSSL engine:
  1. Set FXPKCS11 environment variables.
  2. Explore some OpenSSL Engine examples.

​
Set FXPKCS11 environment variables

In a terminal, run the following sequence of commands to set the required FXPKCS11 environment variables:
Shell
export FXPKCS11_MODULE=/path/to/libfxpkcs11.so;
export FXPKCS11_CFG=/path/to/fxpkcs11.cfg;

​
Create a key pair

Perform the following steps to create a key pair on the Vectera Plus by using pkcs11-tool:
1
In a terminal, run the following command to use pkcs11-tool to create a new key pair on the Vectera Plus:
Shell
pkcs11-tool --module $FXPKCS11_MODULE --login --keypairgen --key-type rsa:2048 --label "my_rsa2048_key" --id "123456" --usage-sign --usage-decrypt
2
Enter the password of the identity configured in the fxpkcs11.cfg file when prompted for the User PIN.
If the command succeeds, the keys display in the output, as shown in the following example:
Shell
Key pair generated:
Private Key Object; RSA 
  label:      myrsa2048key
  ID:         123456
  Usage:      decrypt, sign, unwrap
  Access:     sensitive, local
Public Key Object; RSA 2048 bits
  label:      myrsa2048key
  ID:         123456
  Usage:      encrypt, verify, wrap
  Access:     local
The command creates the following keys, which the next section uses in the test OpenSSL commands:
  • A private RSA 2048 key with asymmetric sign and verify usage
  • A public RSA 2048 key with verify usage.

​
OpenSSL example commands

Most of the following OpenSSL example commands use the keys created on the Vectera Plus in the previous section. All the commands that use the keys created on the HSM specify the PKCS11 OpenSSL engine. This section does not provide an exhaustive list of OpenSSL commands that you can run by using the PKCS11 OpenSSL Engine. Instead, it provides a few examples of use cases and confirms that you configured everything correctly. Refer to the OpenSSL documentation (www.openssl.org/docs/) for the full list of compatible commands.

​
Example 1: Output the public key

In a terminal, run the following command to output the public key from the HSM:
Shell
openssl rsa -engine pkcs11 -pubout -inform engine -in "pkcs11:object=my_rsa2048_key"
If the command succeeds, you should see output similar to the following example:
Shell
engine "pkcs11" set.

​
Example 2: Encrypt and decrypt data

Perform the following steps to encrypt data with the public key and decrypt with the HSM stored private key:
1
In a terminal, run the following command to generate a file, clear_data, containing random ASCII data:
Shell
echo "This is a test file" > ./clear_data
2
Retrieve the public key from the HSM.
Shell
openssl rsa -engine pkcs11 -inform ENGINE -in "pkcs11:object=my_rsa2048_key" -pubout -outform PEM -out pubkey.pem
3
Encrypt the clear_data file by using the public key retrieved from the HSM and output the results to a file, encrypted_data.
Shell
openssl pkeyutl -pubin -inkey pubkey.pem -in ./clear_data -encrypt -out ./encrypted_data -pkeyopt rsa_padding_mode:oaep
4
Decrypt the encrypted_data file by using the HSM stored private key and output the results to a file, clear_ data2.
Shell
openssl pkeyutl -engine pkcs11 -keyform engine -inkey "pkcs11:object=my_rsa2048_key" -decrypt -in ./encrypted_data -out ./clear_data2 -pkeyopt rsa_padding_mode:oaep
5
Confirm that the contents of clear_data and clear_data2 files are identical.
Shell
diff clear_data clear_data2

​
Example 3: Sign a file and verify the signature

Perform the following step to sign a data file using the HSM stored private key and verify the signature by using the public key:
1
Sign the clear_data file by using the HSM stored private key and output the signature to a file, clear_data.sig.
Shell
openssl pkeyutl -engine pkcs11 -keyform engine -inkey "pkcs11:object=my_rsa2048_key" -sign -in ./clear_data -out ./clear_data.sig
2
Verify the signature by using the public key.
Shell
openssl pkeyutl -pubin -inkey pubkey.pem -verify -in ./clear_data -sigfile ./clear_data.sig
A message should display on the screen confirming that the signature was verified successfully.

​
Example 4: Create a self-signed Root CA

Perform the following steps to create a self-signed Root CA:
1
Generate a self-signed CA certificate with the HSM stored private key.
Shell
openssl req -new -x509 -engine pkcs11 -keyform engine -key "pkcs11:object=my_rsa2048_key" -out ssl-ca-cert.pem -days 365
2
When prompted, enter information about the self-signed CA certificate.
After you enter the information, the command creates the follwoing file: ssl-ca-cert.pem.

​
Example 5: Generate a CSR

Perform the following steps to generate a CSR:
1
Generate a CSR with the HSM stored private key.
Shell
openssl req -new -engine pkcs11 -keyform engine -key "pkcs11:object=my_rsa2048_key" -out ssl-client-cert-req.pem -days 365
2
When prompted, enter information about the certificate.
After you enter the information, the command creates the following file: ssl-client-cert-req.pem.

​
Example 6: Sign a CSR

Execute the following command to sign a CSR by using the HSM-stored private key:
Shell
openssl x509 -req -engine pkcs11 -in ssl-client-cert-req.pem -CA ssl-ca-cert.pem -CAkeyform engine -CAkey "pkcs11:object=my_rsa2048_key" -CAcreateserial -out signed-client-cert.pem -days 365
The command outputs the signed certificate to the signed-client-cert.pem file.
