Why are the MD5 and earlier variants of SHA not recommended at all for actual use?

The MD5 hash function produces a 128-bit hash value. It was designed for use in cryptography, but vulnerabilities were discovered over the course of time, so it is no longer recommended for that purpose.

Can 2 different files have same checksum?

“Two files can have the same md5 hash only if their contents are exactly the same, even a single bit of variation would generate a completely different hash value.” – This is wrong.

Is MD5 or SHA1 more accurate?

Both MD5 stands for Message Digest and SHA1 stands for Secure Hash Algorithm square measure the hashing algorithms wherever The speed of MD5 is fast in comparison of SHA1’s speed. However, SHA1 provides more security than MD5….Difference between MD5 and SHA1.

S.NO	MD5	SHA1
5.	MD5 is simple than SHA1.	While SHA1 is more complex than MD5.

What is the difference between MD5 and RSA?

MD5 utilizes CPU in an efficient manner by using a fast computation algorithm whereas RSA uses most of the computer resources thus slowing down the speed of encryption. MD5 is an irreversible algorithm as it provides one way has function whereas RSA is a reversible algorithm as we can encrypt as well as decrypt.

Why are MD5 and SHA-1 no longer the preferred algorithm for hash values?

SHA-1 and MD5 are broken in the sense that they are vulnerable to collision attacks. That is, it has become (or, for SHA-1, will soon become) realistic to find two strings that have the same hash.

Is MD5 better than SHA?

SHA is comparatively more secured as a cryptographic hash algorithm than MD5. The MD5 algorithm is much faster than the SHA version. However, the optimized SHA1 version was developed as an improvement over the initial algorithm and is considerably faster than MD5.

Can two MD5 be same?

Yes, it is possible that two different strings can generate the same MD5 hash code.

How does SHA1 differ from MD5?

The main difference between SHA and MD5 is that SHA connotes a cryptographic hash function developed by NIST, while MD5 is a commonly used hash function that produces a 128-bit hash value from a file with a varying string length. SHA is comparatively more secured as a cryptographic hash algorithm than MD5.

Why is Sha 2 better than MD5?

Both of these hash functions are widely used in modern computer systems. The SHA-2 algorithm is used for cryptographic applications such as password storage and as a proof-of-work for the Bitcoin cryptocurrency. The MD5 algorithm is a much faster hashing algorithm but it is not cryptographically secure.

Is MD5 the same as SHA?

The main difference between MD5 and SHA is that MD5 is not cryptographically stronger and not secure while SHA is more cryptographically stronger and secure with versions such as SHA 256 and SHA 512. There are various algorithms used to protect the messages in communication. Two of them are MD5 and SHA.
