Expand description

⚠️ Low-level “hazmat” RSA functions.

☢️️ WARNING: HAZARDOUS API ☢️

This module holds functions that apply RSA’s core encryption and decryption primitives to raw data without adding or removing appropriate padding. A well-reviewed padding scheme is crucial to the security of RSA, so there are very few valid uses cases for this API. It’s intended to be used for implementing well-reviewed higher-level constructions.

We do NOT recommend using it to implement any algorithm which has not received extensive peer review by cryptographers.

Functions

  • rsa_decrypt
    ⚠️ Performs raw RSA decryption with no padding or error checking.
  • rsa_decrypt_and_check
    ⚠️ Performs raw RSA decryption with no padding.
  • rsa_encrypt
    ⚠️ Raw RSA encryption of m with the public key. No padding is performed.
