Tutorials using this tool

How to Build a Secure CI/CD Pipeline

Design a CI/CD pipeline with security gates at every stage: dependency scanning, SAST, DAST, secret detection, and artifact signing.

How to Implement a Secure Enclave

Use hardware-based trusted execution environments (TEEs) like Intel SGX, AMD SEV, and ARM TrustZone to protect code and data in isolated memory enclaves.

How to Implement Secrets Management

Centralize, rotate, and audit cryptographic secrets (API keys, passwords, certificates) using a secrets manager with least-privilege access.

Add UTF-8 BOM to file content.

Compare two file contents — separate them with '---' on its own line. Reports equality plus each side's size in UTF-8 bytes.

UTF-8 Sanitize (Lone Surrogates)

Sanitizes text to valid UTF-8: lone surrogates are replaced with U+FFFD; any other input is returned unchanged. This is not a general encoding converter — GBK/Shift-JIS/Big5 and other encodings are not decoded.
