You can use Python encryption and security libraries to enable surety functions in your applications, such as encryption, key generation, message authentication, and key agreement. 

 

Encryption is a challenging task in web and application development. And a reliable open-source Python encryption library can make the job easier. With the help of these libraries, developers can implement robust security features, secure network communications, and encrypt sensitive data at rest. There are two types of encryption algorithms, which are Symmetric and Asymmetric. For instance, if you need to store or secure a password, it can be useful to implement a strong cryptographic hashing algorithm. On the other hand, you can employ the Advanced Encryption Standard for encrypting something like credit card details. AES is a symmetric-key algorithm, which we federal organizations most prefer. 

 

Various Python libraries can help both encrypt and decrypt the data. We have handpicked the top and trending open-source Python encryption libraries for your applications:

cryptography

  • Used in Security, Cryptography applications, etc.
  • Provides a set of cryptographic primitives.
  • Offers symmetric and asymmetric encryption.
  • Functions include digital signatures and message authentication codes.
  • Supports Python 3.6+ and PyPy3 7.2+.
