1Password vs age

1Password is a password manager developed by AgileBits that stores and manages passwords, software licenses, and other sensitive information in an encrypted vault. It uses end-to-end AES 256-bit encryption with a two-key derivation system combining a master password and Secret Key. The application supports cross-platform use with browser extensions for major browsers and native apps across desktop and mobile operating systems.

age is an open-source file encryption tool and library designed as a modern replacement for GPG. It uses X25519, ChaChaPoly, and HMAC-SHA256 as cryptographic primitives with a simple command-line interface. The tool supports encryption to multiple recipients, SSH key-based encryption, and passphrase-based encryption.
