Internship Task: Text Encryption Tool

🚀 Internship Task: Text Encryption Tool 🔐

As part of my Pinnacle Labs Cybersecurity Internship, I developed a Text Encryption Tool that ensures secure data protection using multiple cryptographic algorithms. The tool allows users to encrypt and decrypt text efficiently, helping to safeguard sensitive information.

You Should Know: Practical Cryptographic Commands

Here are some practical commands and code snippets related to text encryption and decryption using common cryptographic tools:

1. OpenSSL for AES Encryption

Encrypt a file using AES-256-CBC:

openssl enc -aes-256-cbc -salt -in plaintext.txt -out encrypted.txt

Decrypt the file:

openssl enc -d -aes-256-cbc -in encrypted.txt -out decrypted.txt

2. GPG for File Encryption

Encrypt a file using GPG:

gpg -c plaintext.txt

Decrypt the file:

gpg -d plaintext.txt.gpg > decrypted.txt

3. Python Script for Text Encryption

Here’s a Python script using the `cryptography` library to encrypt and decrypt text:

from cryptography.fernet import Fernet

<h1>Generate a key</h1>

key = Fernet.generate_key()
cipher_suite = Fernet(key)

<h1>Encrypt text</h1>

text = b"Sensitive information"
encrypted_text = cipher_suite.encrypt(text)
print("Encrypted:", encrypted_text)

<h1>Decrypt text</h1>

decrypted_text = cipher_suite.decrypt(encrypted_text)
print("Decrypted:", decrypted_text.decode())

4. Hashing with SHA-256

Generate a SHA-256 hash of a file:

sha256sum plaintext.txt

5. Base64 Encoding and Decoding

Encode a file to Base64:

base64 plaintext.txt > encoded.txt

Decode a Base64 file:

base64 -d encoded.txt > decoded.txt

What Undercode Say

Text encryption is a fundamental aspect of cybersecurity, ensuring data confidentiality and integrity. Tools like OpenSSL, GPG, and Python’s `cryptography` library provide robust methods for encrypting and decrypting sensitive information. Always use strong encryption algorithms like AES-256 and securely manage your encryption keys. For further reading, check out these resources:
