# RSA involves a public key and private key.<ref name="ref_29a526de" />

# In RSA, the private key consists of an exponent calculated from the two secret prime numbers using Carmichael's totient function and the extended Euclidean algorithm.<ref name="ref_f8a67544" />
# Because of its slow pace, RSA is not typically used to directly encrypt data.<ref name="ref_f8a67544" />
