QUESTION

The formula for generating decryption key for RSA algorithm is `ed = 1 mod T`

where T is generated using the formula `(p-1)(q-1)`

. p and q are two non identical prime number. e is the Encryption Key. So as per the formula if I like to implement the `ed = 1 mod T`

in C program the code block should be

ANSWER

Answered 2022-Mar-30 at 21:14The modular multiplicative inverse can be found with the extended Euclidean algorithm.

Here is a simple demonstration implementation. Cryptographic implementations generally needed extended-precision arithmetic.

QUESTION

We have been given an assignment part of which requires us to generate a public private key pair. These do not need to be particularly secure, as it is just for demonstration of the concept.

**We can not use any sort of cryptography libraries or external tools.**

How would I go about generating these?

QUESTION

I am porting some code using Intel IPP lib to OpenSSL (Apple Silicon port).

I have some code checking an XML file signature that looks like this:

...ANSWER

Answered 2021-May-05 at 10:58So after a bit more experimenting, I realised that indeed, `ippsRSAVerify_PCKS1v15`

and `RSA_Verify`

expect different data for their respective `pMsg`

and `m`

arguments. The Intel function wants to be given the entire message to sign/verify, and computes the SHA1 digest (or other digest) internally, whereas the OpenSSL function expects to be given the digest of the message to sign/verify, not the original message itself.

## Vulnerabilities

No vulnerabilities reported

## Install RSA-Algorithm

You can use RSA-Algorithm like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
