jwe-encryptify 0.0.3

A Python package to facilitate JSON Web Encryption (JWE) with enhanced security, leveraging AWS Key Management Service (KMS) and Secrets Manager for secure input and output handling.

jwe-encryptify

jwe-encryptify is a Python package designed for secure encryption and decryption using JSON Web Encryption (JWE), enhanced by AWS Key Management Service (KMS) and AWS Secrets Manager integration. This package offers a straightforward solution for handling sensitive data, allowing encrypted data exchange while securely managing encryption keys through AWS.

Features

• Robust Data Encryption: Uses JSON Web Encryption (JWE) to ensure data security and integrity.
• AWS KMS Integration: Leverages AWS KMS for secure key encryption and decryption.
• AWS Secrets Manager: Efficiently manages public and private key pairs for encryption processes.
• User-Friendly API: Simplified methods for secure JSON payload encryption and decryption.

Installation

You can install the package via pip from PyPI:

pip install jwe-encryptify

Usage

• AWS Configuration: Ensure that your AWS credentials and region are set up. The package requires AWS permissions to access KMS and Secrets Manager.
• Environment Variable: Set AWS_DEFAULT_REGION as an environment variable or configure it in your AWS settings.

Encrypting Data using JWE

Use the encrypt method to secure JSON data with a public key stored in AWS Secrets Manager.

from jwe_crypto import encrypt

# Data to encrypt
data_to_encrypt = {"user": "John Doe", "account_id": "123456"}

# Encrypt the data
jwe_encrypted_token = encrypt(
  kms_id="your-kms-key-id",  # AWS KMS key ID for encryption
  secret_name="your-secret-name",  # AWS Secrets Manager secret name
  secret_key="public-key",  # Key name in the secret (public key)
  api_response=data_to_encrypt  # JSON data to encrypt
)
print("Encrypted JWE Token:", jwe_encrypted_token)

Encrypting Data using KMS

Use the encrypt method to secure JSON data using an AWS KMS key.

from kms_crypto import encrypt

# Data to encrypt
data_to_encrypt = {"user": "John Doe", "account_id": "123456"}

# Encrypt the data using KMS
kms_encrypted_value = encrypt(
  kms_id="your-kms-key-id",  # AWS KMS key ID used for encryption
  plaintext=str(data_to_encrypt)  # Convert the JSON data to a string
)

print("Encrypted KMS Value:", kms_encrypted_value)

Decrypting Data using JWE

Use the decrypt method to decrypt an encrypted JWE token using a private key from AWS Secrets Manager.

from jwe_crypto import decrypt

# JWE token to decrypt
jwe_token = "your-encrypted-jwe-token"

# Decrypt the data
decrypted_data = decrypt(
  kms_id="your-kms-key-id",  # AWS KMS key ID
  secret_name="your-secret-name",  # AWS Secrets Manager secret name
  secret_key="private-key",  # Key name in the secret (private key)
  jwe_payload=jwe_token  # Encrypted JWE payload
)

print("Decrypted Data:", decrypted_data)

Decrypting Data using KMS

Use the decrypt method to decrypt an encrypted value using an AWS KMS key and encryption context.

from kms_crypto import decrypt

# Encrypted value to decrypt
encrypted_value = "your-encrypted-kms-value"

# Decrypt the data using KMS
decrypted_data = decrypt(
  kms_id="your-kms-key-id",  # AWS KMS key ID used for decryption
  lambda_function_name="your-lambda-function-name",  # Encryption context
  encrypted_value=encrypted_value  # Encrypted value to decrypt
)

print("Decrypted Data:", decrypted_data)

AWS Permissions

Ensure the following permissions are assigned to your AWS IAM role or user:

• KMS Permissions:
  • kms:Encrypt
  • kms:Decrypt
• Secrets Manager Permissions:
  • secretsmanager:GetSecretValue

Dependencies

The package requires the following dependencies:

• jwcrypto: For JWE encoding and decoding.
• boto3: AWS SDK for Python.
• botocore: Core library used by boto3. Install all dependencies automatically via pip install jwe-encryptify.
