Cryptengine is a supercomputing-based password analysis service provided by South Korea’s Easternware. Its core function is to use the company’s own EHK7 supercomputer to help users recover passwords for encrypted documents or hashes. It is closer to a “password recovery / digital forensics assistance service” than to proactive security products such as firewalls, EDR, or zero trust. The service targets users who have forgotten passwords for old documents, supporting either the return of an unlocked file or, in higher-tier plans, the password itself.
The service is divided into Free, Basic, Advanced, Expert, and Rental tiers. Free allocates up to 30 minutes of resources, Basic up to 12 hours, Advanced up to 3 days, and Expert up to 7 days. Free/Basic mainly return the file with the password removed, while Advanced/Expert return the password. Advanced and above support HWP, ZIP, ALZIP, MS Word, PowerPoint, Excel, Hancom Cell, Hancom Show, MD5, SHA1/2, and more. A key highlight of Expert is that it does “not transmit the original document,” making it more suitable for sensitive materials. Rental leases a supercomputer on an annual basis and runs it remotely in the customer’s office through dedicated software.
Pricing is disclosed relatively clearly: Free is free, Basic is 50,000 KRW per file, Advanced is 300,000 KRW per file, Expert is 1,000,000 KRW per file, and Rental is 20,000,000 KRW per unit per year. The text also states that paid services are only charged when password decryption succeeds, which is user-friendly for password recovery scenarios where the outcome is uncertain. It is suitable for individuals, corporate records management departments, data recovery teams, and highly sensitive organizations that need to avoid sending original documents externally.
The advantages are that the service tiers, resource duration, supported formats, and pricing are all described fairly clearly, and it offers a free trial plus a success-based charging model. Expert and Rental also balance security needs with computing power requirements. The drawbacks are that the text does not explain file ownership verification, anti-abuse procedures, data deletion policies, transmission encryption, access control, audit logs, or compliance certifications, nor does it disclose API or enterprise integration capabilities. For cybersecurity procurement, these are important gaps.
Access from mainland China, payment methods, and Chinese-language support are not reflected in the text, so china_access can only be assessed as unknown. If cross-border access or KRW payments are inconvenient, alternatives to consider include Passware Kit, Elcomsoft, self-hosted compute using Hashcat/John the Ripper, or domestic compliant data recovery and digital forensics service providers.
