What are the differences between hash functions in Python?
In Python, common hash functions include MD5, SHA-1, and SHA-256. MD5 is fast but not secure, while SHA-256 is more secure but slower.
Can you explain why MD5 is considered insecure?
MD5 is vulnerable to collision attacks, where two different inputs produce the same hash. This makes it unsuitable for security purposes.
What are some use cases for SHA-256?
SHA-256 is widely used in blockchain technology, digital signatures, and certificate generation due to its strong security.
How do I implement these hash functions in Python?
You can use the hashlib
library in Python. For example, import hashlib; hashlib.sha256(b'your data').hexdigest()
will give you the SHA-256 hash.
