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.
