: RSA uses two distinct keys: a public key for encryption (known to everyone) and a private key for decryption (kept secret by the owner).
(encryption exponent) is chosen such that it is relatively prime to . The public key is the pair : A private exponent RSA and Public Key Cryptography Cryptography

: To maintain security against modern computing power, it is recommended to use a minimum key length of 2048 bits . Primary Use Cases : To maintain security against modern computing power,
: Its security relies on the "factoring problem" —the extreme computational difficulty of factoring a very large number back into its original two large prime numbers.
