# AGEX Passphrase Strength Checker Evaluate a passphrase for AGEX file bundles and recommend the most suitable protection profile > Canonical page: https://elysiatools.com/en/tools/agex-passphrase-strength-checker - **Category:** Security - **Keywords:** agex, passphrase strength, argon2id, bundle security, password checker ## Overview This tool focuses on passphrases used with AGEX portable file bundles. It looks at length, entropy, composition, and predictable patterns, then maps the result to an AGEX-friendly Argon2id preset recommendation. ## Inputs - **Passphrase** (text): Enter the passphrase you plan to use for the AGEX bundle ## When to use - Before encrypting sensitive AGEX file bundles to ensure the passphrase meets security requirements. - When choosing between interactive, moderate, or sensitive Argon2id protection profiles for your bundle. - To identify predictable patterns or weak entropy in a planned passphrase before deployment. ## How it works - Input your proposed passphrase into the text field. - The tool analyzes the passphrase's length, entropy, composition, and pattern predictability. - It outputs a JSON result indicating the strength level and the recommended AGEX Argon2id profile. ## Use cases - Verifying passphrase complexity before archiving confidential company data in an AGEX bundle. - Determining the correct Argon2id resource limits (interactive vs. sensitive) for automated backups. - Auditing user-generated passphrases to enforce organizational security policies for portable bundles. ## Frequently asked questions ### What does this tool evaluate? It evaluates passphrase length, entropy, composition, and patterns to recommend an AGEX Argon2id profile. ### What are the recommended AGEX profiles? The tool recommends either interactive, moderate, or sensitive profiles based on passphrase strength. ### Does this tool store my passphrase? No, the passphrase is processed locally to evaluate strength and is not stored. ### What is Argon2id? Argon2id is the key derivation function used by AGEX to secure file bundles against brute-force attacks. ### Can I use a weak passphrase with a sensitive profile? It is not recommended, as a weak passphrase undermines the security provided by the sensitive Argon2id profile. ## Related tools - [Security Headers Checker](https://elysiatools.com/en/tools/security-headers-checker): Audit HTTP response headers for security compliance — parses the raw headers you paste (no network) and grades them against the OWASP secure-header set with value-level checks: HSTS max-age, CSP unsafe-inline/eval, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP/COEP/CORP and more. Outputs a letter grade (A+ to F) plus per-header findings with copy-ready fix recommendations. - [URL Safety Checker](https://elysiatools.com/en/tools/url-safety-checker): Detect phishing and fraud signals in a URL by deep structural analysis — punycode/IDN homograph attacks (mixed Latin/Cyrillic), embedded credentials (user:pass@host trick), high-risk TLDs, double-encoding and control-character smuggling, subdomain brand deception, and numeric/IP host obfuscation. Static analysis only, no network. Complements the URL Validator (which does basic protocol/IP checks). - [Env File Secret Rotation Planner](https://elysiatools.com/en/tools/env-file-secret-rotation-planner): Paste a .env file and get a staged secret-rotation plan. Detects database URLs, API keys, auth tokens, private keys, cloud credentials, payment keys and encryption secrets, scores each by exposure and age, and schedules them across a 4-week rotation timeline with a dual-key checklist and a generated .env.example. Optional last-rotated dates and a configurable cadence (30/90/180/365 days) drive compliance scoring. - [Password Validator](https://elysiatools.com/en/tools/password-validator): Validate password strength and check against common security requirements - [ML-KEM / Kyber Keypair & Encapsulation Tester](https://elysiatools.com/en/tools/ml-kem-kyber-keypair-and-encapsulation-tester): Generate ML-KEM-512/768/1024 (FIPS 203 / CRYSTALS-Kyber) keypairs, encapsulate a random shared secret against the public key, decapsulate it with the private key, and verify both sides match — with the exact wire sizes of all three parameter sets checked live against the standard. - [AGEX Keypair Generator](https://elysiatools.com/en/tools/agex-keypair-generator): Generate an Ed25519 keypair for AGEX bundle signing and verification - [Audio Dictation Quality Checker](https://elysiatools.com/en/tools/audio-dictation-quality-checker): Check whether audio is suitable for transcription using SNR, clipping, format, channels, and speech activity. - [Accessibility Audit Report Generator](https://elysiatools.com/en/tools/accessibility-audit-report-generator): Audit HTML or a URL for common WCAG issues and export a structured PDF report grouped by severity ## Samples - [Android Image Processing Java Samples](https://elysiatools.com/en/samples/android-image-processing-java): Android Java image processing examples including reading/saving images, scaling, and format conversion - [Android Image Processing Kotlin Samples](https://elysiatools.com/en/samples/android-image-processing-kotlin): Android Kotlin image processing examples including reading/saving images, scaling, and format conversion - [Web Image Processing Python Samples](https://elysiatools.com/en/samples/web-image-processing-python): Web Python image processing examples using PIL/Pillow including reading, saving, resizing, and format conversion - [Web Image Processing Rust Samples](https://elysiatools.com/en/samples/web-image-processing-rust): Web Rust image processing examples including image read/save, scaling, and format conversion ## Related content - [AGEX Secure File Packaging and Handoff](https://elysiatools.com/en/hubs/agex-secure-file-sharing): Package a file as AGEX, inspect visible metadata, choose passphrase and signature settings, and verify the handoff before delivery.
