Open CLU file

The clu file extension is also used in Broken Sword 2, an adventure game relased in 1997

The clu file contains dialogues, text data used in the game.

Example: TEXT.CLU

The clu file extension is associated with IBM PCI cryptographic coprocessor. Code file.

The IBM 4758 PCI Cryptographic Coprocessor adds a high-security environment to your Windows NT, Windows 2000, AIX, OS/400, z/OS, and OS/390 server systems for DES, RSA, and DSA cryptographic functions and sensitive custom applications. The PCI board incorporates specialized electronics to off-load your servers from time-consuming cryptographic functions while providing a tamper-responding, secure computing environment for the storage of keys and performing sensitive processing. Certification of the hardware under FIPS PUB 140-1 at levels 3 and 4 assures a high-integrity processing environment.

The IBM 4758 PCI Cryptographic Coprocessor product provides high-security cryptography and secure computing for all IBM server platforms and many personal computers. The tamper-responding design has been certified under the USA FIPS 140-1 standard at levels 3 and 4, and has received German ZKA approval for critical financial transaction system processing on z900 Servers.

The IBM 4758 PCI Cryptographic Coprocessor encapsulates a 486-class processing subsystem within a tamper-sensing and tamper-responding environment where you can run security-sensitive processes. A multi-tasking control program gives you access to high performance electronics for DES and public key algorithms. A cryptographic quality random number generation facility and large, secure, persistent data storage complete the physical system. Except for a very small bootstrap loader, all software is loaded into the coprocessor from your server environment. Only digitally signed software that is validated by the coprocessor is acceptable. The sophisticated code loading controls enable you to employ signed software from IBM, other vendors, or code that you create using toolkits available from IBM.

IBM supplies two cryptographic-system implementations, and toolkits for custom application development.

• The PKCS #11, version 2.01 implementation creates a high-security solution for application programs developed for this industry-standard API.
• The IBM Common Cryptographic Architecture implementation provides many functions of special interest in the finance industry and a base on which custom processing and cryptographic functions can be added.
