[Reference: NIST SP 800-57, Recommendation for Key Management., Strong Security:, RSA provides strong security through its use of large key sizes (typically 2048 bits or higher), making it resistant to brute force and other cryptographic attacks., Reference: RSA Laboratories' "PKCS #1: RSA Cryptography Specifications.", International Acceptance:, RSA is widely used and accepted internationally, making it suitable for PolarFin's requirements to comply with various global financial regulations., Reference: ISO/IEC 18033-2:2006, Information technology — Security techniques — Encryption algorithms., Encryption and Decryption:, RSA supports secure encryption of data, ensuring confidentiality, and decryption, allowing authorized parties to access the encrypted information., Reference: "Applied Cryptography" by Bruce Schneier., Given the need for strong security and international acceptance, RSA is the best cryptographic algorithm for PolarFin's new transactional system., , ]
