这是什么? Crypto DLL?

The term "Crypto" in the context of DLL (Dynamic Link Library) files generally refers to a collection of system libraries that are specifically designed for cryptographic purposes. These DLLs support various encryption and decryption operations, digital signature verification, key management, and secure communications within applications or operating systems. Common functions include symmetric and asymmetric encryption algorithms, hash functions, and random number generation for cryptographic use cases. Examples of such DLLs may be integrated into security software, browser components, and system utilities to enhance data protection and integrity.
