Introduction

In this tutorial we learn how to install python3-pycryptodome on Ubuntu.

What is `python3-pycryptodome`

python3-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
Elliptic curves cryptography (NIST P-256, P-384 and P-521 curves only)
Better and more compact API (nonce and iv attributes for ciphers, automatic generation of random nonces and IVs, simplified CTR cipher mode, and more)
SHA-3 (including SHAKE and cSHAKE XOFs), truncated SHA-512 and BLAKE2 hash algorithms
Salsa20 and ChaCha20/XChaCha20 stream ciphers
Poly1305 MAC
ChaCha20-Poly1305 and XChaCha20-Poly1305 authenticated ciphers
scrypt, bcrypt and HKDF derivation functions
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)
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 3 version of the package.

There are three methods to install python3-pycryptodome on Ubuntu. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.

Install python3-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 python3-pycryptodome using apt-get by running the following command:

sudo apt-get -y install python3-pycryptodome

Install python3-pycryptodome Using apt

Update apt database with apt using the following command.

sudo apt update

After updating apt database, We can install python3-pycryptodome using apt by running the following command:

sudo apt -y install python3-pycryptodome

Install python3-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 python3-pycryptodome using aptitude by running the following command:

sudo aptitude -y install python3-pycryptodome

How To Uninstall python3-pycryptodome on Ubuntu
