RSA Overview:

RSA is a widely accepted and strong public-key cryptographic algorithm that supports both

encryption and decryption functions. It is based on the mathematical difficulty of factoring large

prime numbers.

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.
