PearPass

PearPass is an open-source password manager that operates locally. It stores and encrypts credentials directly on the user's device, without external servers. Synchronization is done through point-to-point connections between devices controlled by the user.

• Local storage. The password database is stored exclusively on the user's physical device. Data is not transferred to cloud servers or third-party infrastructures. Encryption is applied directly to the local file.
• P2P synchronization. Transfers data between devices using direct, encrypted connections. Synchronization uses a peer-to-peer network without intermediaries. Each device must be previously authorized by the user.
• End-to-end encryption. Uses cryptographic primitives from Libsodium. The encryption process occurs before any data transfer. Encryption keys are derived from the user's master password.
• External audit. The source code was reviewed by the firm Secfault Security. The audit report covered the cryptographic implementation and security protocols. The results are publicly accessible.
• Offline operation. Works without needing an internet connection. All operations run locally. Access to the keychain is available at any time.
• Password generator. Creates random sequences with configurable parameters. Allows defining length and character types. Includes a strength estimator based on entropy.
• Lightweight architecture. The software has minimal system resource consumption. Startup and searches within the database have reduced response times. It does not include non-essential background processes.
• Data export. Offers the function to export the database in standardized formats. The export can be protected with an additional password. Exported data maintains its original encryption.
• Import from other managers. Supports migration from applications like KeePass or Bitwarden. Automatically converts file formats. Preserves metadata during the transfer process.
• Auto-self-destruct after failed attempts. Activates a self-destruct protocol after multiple incorrect entries of the master password. The attempt threshold is configurable by the user. This function protects against physical brute-force attacks.
• Clipboard encryption. Automatically clears the clipboard after a defined time interval. This mechanism prevents temporary passwords from being captured by malicious software. The clearing interval is adjustable.
• Read-only mode. Allows opening the database without allowing modifications. This mode is useful for reviewing credentials in environments with potential risk. Write functions are disabled.

Development of PearPass began in 2022. The creators are a team of developers focused on digital privacy and computer security. The program is written in the Rust programming language. The choice of Rust was based on its memory management and system-level security features. The first public version was released in late 2023.
