#CryptoSecurity101 *Crypto Security 101*

Cryptographic security relies on:

1. *Encryption:* Protects data confidentiality (e.g., AES).

2. *Digital Signatures:* Ensures authenticity and integrity (e.g., RSA, ECDSA).

3. *Hash Functions:* Verifies data integrity (e.g., SHA-256).

*Key Principles:*

1. *Confidentiality:* Protect data from unauthorized access.

2. *Integrity:* Ensure data isn't modified without detection.

3. *Authenticity:* Verify sender/receiver identity.

*Best Practices:*

1. Use secure protocols (e.g., HTTPS, SSH).

2. Implement strong passwords and authentication.

3. Regularly update software and libraries.

*Common Threats:*

1. *Man-in-the-middle (MITM) attacks*

2. *Side-channel attacks*

3. *Brute-force attacks*

*Stay Secure:*

1. Stay informed about security updates.

2. Use reputable sources for cryptographic libraries.

3. Follow security guidelines and standards.
