For details on key formats, see Public key format. Generating an RSA key. You can generate a 2048-bit RSA key pair with the following commands: openssl genpkey -algorithm RSA -out rsaprivate.pem -pkeyopt rsakeygenbits:2048 openssl rsa -in rsaprivate.pem -pubout -out rsapublic.pem These commands create the following public/private key pair.

2. Mar 03, 2020 You can use the following commands to generate a P-256 Elliptic Curve key pair: openssl ecparam -genkey -name prime256v1 -noout -out ecprivate.pem openssl ec -in ecprivate.pem -pubout -out ecpublic.pem These commands create the following public/private key pair.
3. Generating key pairs with OpenSSH¶ Another tool that you can use to generate key pairs is ssh-keygen, which is a tool included in the SSH suite that is specifically used to create and manage SSH keys. As SSH keys are standard asymmetrical keys we can use the tool to create keys for other purposes. To create a key pair just run.

Private/public key pairs enable agents and the users' devices to create messagehashes specific to conversations with each other. By using private/public keypairs, agents and the Message app can compute shared secrets and securely hashmessage content, making the content unreadable to Verified SMS and Google.

After you create anagent, you need tocreate the agent's key pair and update the agent's publickey with Verified SMS. Once your agent is running, you need toget users' public keys before you can send them verified messages.

User public keys

When you're ready to send a verified message, you need to get the recipient'spublic key before you can create and store the messagehash. You canget up to 10,000 public keys in a single API call.

Get users' public keys before every message. Otherwise,your messages may appear as unverified.

Occasionally, the Messages app rotates public keys, so you need to get a user'spublic key before sending them any message, even if you've sent verifiedmessages to the user previously. If you create a message hash with an outdatedpublic key, the Messages app generates a hash with the current public key,resulting in a hash mismatch. If Verified SMS can't match message hashes, yourmessage appears as unverified.

The Verified SMS Sample and SDK can get user public keys when you store hashes.If you choose to not use the Sample and SDK, the following code gets one or moreusers' public keys. For formatting and value options, seeuserKeys.batchGet.

Agent private/public key pairs

Agents use their private keys and users' public keys during messaging hashing toobfuscate message content, and the Messages app uses users' private keys andagents' public keys. For a Verified SMS agent to function, the agent needs tocreate a key pair and share its current public key with Verified SMS so thatthe Message app can access it.

Create an agent's key pair

To create a key pair for your agent, run the following commands in a terminal.

The commands generate three files:

Openssl Generate Key Pair Pkcs8 Key

• verified-sms-agent_name-private-key-P-384.pem is aprivate key in PEM format that isn't used but is important to keep as areference.
• verified-sms-agent_name-private-key-P-384-pkcs8.deris a private key used by the SDK to create message hashes. Don't share thiskey with Verified SMS.
• verified-sms-agent_name-public-key-P-384.der is a public key used by theMessages app to create message hashes for messages from your agent. Requiredto create your agent.

Store your private key files somewhere secure but available to yourinfrastructure. Never share your private keys.

Now that you've created keys for your agent, you need to update your agent'spublic key with Verified SMS.

Update an agent's public key

You can change your agent's private/public key pair at any time. Whether tocomply with security requirements or rotate out a compromised key pair, updatingyour agent's key is as simple as creating a new key pair andupdating your agent's public key with Verified SMS.

Note:

Openssl Generate Public Private Key

Verified SMS can only use an agent's three most recent public keys toverify messages. If a user receives a message that an agent hashed with a keythat is more than three keys old, the message appears as unverified.

Consider updating keys no more than once per week so that all hashes for thethree previous weeks remain valid in case of late message delivery.

The following code updates an agent's public key. For formatting and valueoptions, seeagents.updateKey.

Get an agent's public key

If you're unsure which public key is registered with Verified SMS, you can getthe agent's current registered public key. If the public key from the key pairyou're using with your agent doesn't match the public key registered withVerified SMS, hashes you create and store may not be valid and may result inunverified messages.

The key registered with Verified SMS might not match your public key for tworeasons:

• You're using an old public/private key pair. Locate and use the key pairthat matches the public key registered with Verified SMS.
• You created a new key pair but didn't update the public key with VerifiedSMS. Update your public key.

When the public keys match, you're ready to begin hashingmessages.

The following code gets an agent's public key. For formatting and value options,seeagents.getKey.

Next steps

Now that your agent can fetch user public keys and has a public key registeredwith Verified SMS, you're ready to configure messagehashing. Cisco 3850 generate rsa key.
