Crypto Key Generate Rsa Modulus

Posted on by

I am newbie in cryptography and pycrypto. I have modulus n and private exponent d. From what I understand after reading some docs private key consists of n and d. I need to sign a message and I can't figure out how to do that using pycrypto. RSA.construct method accepts a tuple. Finally, here is some code to actually factor the modulus, given a valid RSA key: import random import fractions # Returns a tuple (p, q) that are # the prime factors of N, given an # RSA key (e, d, N) def factorrsa(e, d, N): k = e.d - 1 y = None while not y: x = random.randrange(2, N) y = getrootone(x, k, N) p = fractions.gcd(y-1, N) q = N. Generate a RSA crypto key using a modulus of 1024 bits. R1(config)# crypto key generate rsa modulus 1024 The name for the keys will be: R1.CCNA-lab.com% The key modulus size is 1024 bits% Generating 1024 bit RSA keys, keys will be non-exportable.

You may generate an RSA private key with the help of this tool. Additionally, it will display the public key of a generated or pasted private key.

Description

RSA is an asymmetric encryption algorithm. With a given key pair, data that is encrypted with one key can only be decrypted by the other. This is useful for encrypting data between a large number of parties; only one key pair per person need exist. Trusted platform module 1.2 driver windows 7. RSA is widely used across the internet with HTTPS.

To generate a key pair, select the bit length of your key pair and click Generate key pair. Depending on length, your browser may take a long time to generate the key pair. A 1024-bit key will usually be ready instantly, while a 4096-bit key may take up to several minutes. For a faster and more secure method, see Do It Yourself below.

CryptoTools.net does not yet have a tool for facilitating the encryption and decryption of data using RSA, but you may Do It Yourself with the instructions below.

Do It Yourself

For these steps, you will need a command line shell with OpenSSL. Ideally, you should have a private key of your own and a public key from someone else. For demonstration, we will only use a single key pair.

Generate Private Key

Modulus

Run this command to generate a 4096-bit private key and output it to the private.pem file. If you like, you may change the key length and/or output file.

Derive Public Key

Given a private key, you may derive its public key and output it to public.pem using this command. (You may also paste your OpenSSL-generated private key into the form above to get its public key.)

Encrypt Data

We can now use this key pair to encrypt and decrypt a file, data.txt.

Decrypt Data

Given the encrypted file from the previous step, you may decrypt it like so.

While reconfiguring a Cisco switch 3750G WS-C3750G-24TS-S1U with version 12.0(5.3). When attempting to run “crypto key genearte rsa“, it was failing with below error:

MW-CORE-SW01#conf t
Enter configuration commands, one per line. End with CNTL/Z.
MW-CORE-SW01(config)#hostname MWired
MW-CORE-SW01(config)#ip domain-name magwinya.co.za
MW-CORE-SW01(config)#crypto key generate rsa

% Invalid input detected at ‘^’ marker.

Workaround Solution:

In order to run “crypto key generate rsa”, you need an IOS image that contains “k9” in the name.

In our case we had to upgrade IOS boot image to:

c3750-advipservicesk9-mz.122-46.SE.bin

Once upgrade is completed, all was in order.
