How To Install python-pycryptodome on Ubuntu 20.04
Introduction
In this tutorial we learn how to install python-pycryptodome
on Ubuntu 20.04.
What is python-pycryptodome
python-pycryptodome is:
PyCryptodome is a self-contained Python package of low-level cryptographic primitives.
PyCryptodome is a fork of PyCrypto. It brings several enhancements with respect to the last official version of PyCrypto (2.6.1), for instance:
- Authenticated encryption modes (GCM, CCM, EAX, SIV, OCB)
- Accelerated AES on Intel platforms via AES-NI
- First class support for PyPy
- Elliptic curves cryptography (NIST P-256 curve only)
- Better and more compact API (
nonce
andiv
attributes for ciphers, automatic generation of random nonces and IVs, simplified CTR cipher mode, and more) - SHA-3 (including SHAKE XOFs) and BLAKE2 hash algorithms
- Salsa20 and ChaCha20 stream ciphers
- scrypt and HKDF
- Deterministic (EC)DSA
- Password-protected PKCS#8 key containers
- Shamir’s Secret Sharing scheme
- Random numbers get sourced directly from the OS (and not from a CSPRNG in userspace)
- Simplified install process, including better support for Windows
- Cleaner RSA and DSA key generation (largely based on FIPS 186-4)
- Major clean ups and simplification of the code base
PyCryptodome is not a wrapper to a separate C library like OpenSSL. To the largest possible extent, algorithms are implemented in pure Python. Only the pieces that are extremely critical to performance (e.g. block ciphers) are implemented as C extensions.
This is the Python 2 version of the package.
There are three methods to install python-pycryptodome
on Ubuntu 20.04. We can use apt-get
, apt
and aptitude
. In the following sections we will describe each method. You can choose one of them.
Install python-pycryptodome Using apt-get
Update apt database with apt-get
using the following command.
sudo apt-get update
After updating apt database, We can install python-pycryptodome
using apt-get
by running the following command:
sudo apt-get -y install python-pycryptodome
Install python-pycryptodome Using apt
Update apt database with apt
using the following command.
sudo apt update
After updating apt database, We can install python-pycryptodome
using apt
by running the following command:
sudo apt -y install python-pycryptodome
Install python-pycryptodome Using aptitude
If you want to follow this method, you might need to install aptitude first since aptitude is usually not installed by default on Ubuntu. Update apt database with aptitude
using the following command.
sudo aptitude update
After updating apt database, We can install python-pycryptodome
using aptitude
by running the following command:
sudo aptitude -y install python-pycryptodome
How To Uninstall python-pycryptodome on Ubuntu 20.04
To uninstall only the python-pycryptodome
package we can use the following command:
