What are the different types of hash functions in C++?
In C++, common types of hash functions include MD5, SHA-1, and SHA-256. Each has different use cases and security levels.
Can you explain the differences between MD5 and SHA-256?
MD5 produces a 128-bit hash value and is faster but less secure, while SHA-256 produces a 256-bit hash and is more secure.
When should I use SHA-256 over MD5?
Use SHA-256 when security is a priority, such as in cryptographic applications, while MD5 may be suitable for checksums.
Are there any libraries in C++ for implementing these hash functions?
Yes, libraries like OpenSSL and Crypto++ provide implementations for various hash functions, including MD5 and SHA-256.
