Question 1

Is RIPEMD-160 secure?

Accepted Answer

RIPEMD-160 is considered more secure than MD5 and slightly more secure than SHA-1 against collision attacks, but it's not recommended for new security-critical applications. Use SHA-256 or SHA-3 for better security.

Question 2

Why is RIPEMD-160 used in Bitcoin?

Accepted Answer

Bitcoin uses RIPEMD-160 in combination with SHA-256 (SHA-256 followed by RIPEMD-160) to create shorter addresses. This was a design choice to keep addresses manageable while maintaining security.

Question 3

What is the output length?

Accepted Answer

RIPEMD-160 always produces a 160-bit hash, represented as 40 hexadecimal characters.

Question 4

Can I hash files?

Accepted Answer

This tool is designed for text input. For hashing files, use the File Hash Checker tool which supports SHA-256, MD5, and other algorithms.

Question 5

What is the difference between RIPEMD-160 and SHA-1?

Accepted Answer

Both produce 160-bit hashes, but they use different algorithms. SHA-1 is more widely used but has known collision vulnerabilities. RIPEMD-160 is less common but has held up slightly better against cryptanalysis, though both are considered legacy for new applications.
