The '''IBM 4758''' PCI Cryptographic Coprocessor is a [[secure cryptoprocessor]] implemented on a high-security, tamper resistant, programmable [[Peripheral Component Interconnect|PCI]] [[expansion card]]. Specialized cryptographic electronics, [[microprocessor]], [[Random Access Memory|memory]], and [[random number generator]] housed within a tamper-responding environment provide a highly secure subsystem in which [[data processing]] and [[cryptography]] can be performed. 

[[IBM]] supplies two cryptographic-system implementations, and toolkits for custom application development:
* The [[PKCS11|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. 

As of June 2005, the 4758 was discontinued and was replaced by an improved, faster model called the [[IBM 4764]].
