Data encryption

Jobs tagged with Data encryption focus on securing sensitive information within PHP applications. This critical security practice involves converting data into a coded format to prevent unauthorized access, ensuring the confidentiality and integrity of user information, application secrets, and other private data.

A developer in this role is expected to build and maintain systems that protect data both at rest (in a database or filesystem) and in transit (over a network). This requires a deep understanding of cryptographic principles and secure implementation practices.

Responsibilities in Data Encryption

Core tasks often involve selecting appropriate encryption algorithms, managing cryptographic keys securely, and ensuring compliance with regulations like GDPR or HIPAA.

• Implementing strong, industry-standard encryption algorithms for storing sensitive data.
• Utilizing PHP's password_hash() and password_verify() functions for secure password management.
• Securing data in transit using TLS/SSL configurations.
• Managing the lifecycle of encryption keys, including generation, storage, and rotation.
• Integrating with hardware security modules (HSMs) or cloud-based key management services.

Essential Skills and Technologies

Proficiency with PHP's security features and related libraries is paramount.

• Strong knowledge of the OpenSSL extension in PHP.
• Experience with cryptographic libraries like defuse/php-encryption or libsodium.
• Understanding of symmetric vs. asymmetric encryption, hashing, and digital signatures.
• Familiarity with secure coding practices to prevent vulnerabilities.
