How does SHA-1 help in detecting data tampering?
How does SHA-1 help in detecting data tampering?
- By allowing for reversible hashing operations
- By generating the same hash for any input changes
- By producing irreversible hash values (correct)
- By changing the input data length
Why has SHA-1's effectiveness been questioned in recent years?
Why has SHA-1's effectiveness been questioned in recent years?
- Because it generates different output sizes for the same input
- Due to its dependence on input complexity
- Because it is not a one-way hash function
- As a result of vulnerabilities discovered and advances in computational power (correct)
