P-384 is a cryptographic algorithm that belongs to the family of elliptic curve cryptography (ECC). It is designed to provide a high level of security while using smaller key sizes compared to traditional methods like RSA. Specifically, P-384 uses a 384-bit key, making it suitable for applications requiring strong security, such as digital signatures and secure communications. The P-384 curve is part of the NIST (National Institute of Standards and Technology) recommended curves, which are widely used in various security protocols, including TLS (Transport Layer Security) and SSH (Secure Shell). Its efficiency and robustness make it a popular choice for securing sensitive data in modern computing environments.
