WebFeb 7, 2024 · Decryption is the process of converting ciphertext back to plaintext. To encrypt more than a small amount of data, symmetric encryption is used. A symmetric key is used during both the encryption and decryption processes. To decrypt a particular piece of ciphertext, the key that was used to encrypt the data must be used. WebThe Decrypt operation also decrypts ciphertext that was encrypted outside of KMS by the public key in an KMS asymmetric KMS key. However, it cannot decrypt symmetric …

WebUsing the repeated squaring as mentioned in the other post: 38191 90043 ≡ 38191 ⋅ ( 38191 2) 45021. (all modulo n of course) We can compute the square of 38191 (modulo n) as 1125. So we need 1125 45021 which equals 1125 ⋅ ( 1125 2) 22510. Then 1125 2 = 57815 modulo n again. So we are reduced to finding ( 57815) 22510 = ( 57815 2) 11255 ...
