What is the encryption standard for the RecPub and RecPrv keys in CyberArk?

The encryption standard for the RecPub and RecPrv keys in CyberArk is RSA 2048. This level of encryption provides a robust balance between security and performance, as RSA 2048 is widely recognized as sufficiently secure for protecting sensitive data while still being efficient enough for use in various applications and systems.

RSA, which stands for Rivest-Shamir-Adleman, is a public key cryptographic system that utilizes two keys: a public key (RecPub) for encryption and a private key (RecPrv) for decryption. The choice of 2048 bits as the standard is in alignment with contemporary best practices in cybersecurity, as it meets the current standards recommended by various security organizations and regulatory guidelines.

Choosing a smaller key size, such as 1024 bits, would be less secure in current contexts, as increasing computational power has made it easier to break smaller keys. Conversely, larger key sizes, such as 3072 or 4096 bits, offer additional security but can lead to increased computational overhead and latency, which is often unnecessary for most practical applications where 2048 bits remains adequate for strong protection against potential threats.
