age:tldr:fc210

This command is likely a simplified representation of a command used to encrypt a file using the recipients' public keys.

Here's a breakdown of the command:

• age: It is the name or alias of the command-line tool or program used to perform cryptographic operations.
• --recipient ${public_key_1}: This flag specifies the first recipient's public key. The variable ${public_key_1} should be replaced with the actual value of the public key. Public keys are used for encryption and anyone possessing the corresponding private key can decrypt the encrypted file.
• --recipient ${public_key_2}: This flag specifies the second recipient's public key. The variable ${public_key_2} should be replaced with the actual value of the public key. This allows multiple recipients to be specified.
• ${path-to-unencrypted_file}: This is the path to the unencrypted file that you want to encrypt. Replace ${path-to-unencrypted_file} with the actual location or filename of the file.
• --output ${path-to-encrypted_file}: This flag specifies the path where the encrypted file will be saved. Replace ${path-to-encrypted_file} with the actual location or filename for the encrypted file.

Overall, this command takes an unencrypted file, encrypts it using the specified recipients' public keys, and generates an encrypted file as output. The resulting encrypted file can only be decrypted by individuals possessing the corresponding private keys associated with the provided public keys.
