Comparing Hash Algorithms: Md5, Sha1 or … 2013-4-2 · Some collision attacks against Sha1 exist but are not currently practical as the CPU power required is estimated as costing almost $3 million for each hash. Even if Sha1 can be considered acceptable for most uses, Sha2 is all-around a better alternative : it is just as fast, more secure, and the only potential downside is the larger space required for storing the hash.

SHA1 Collision Signals the End of the Algorithm’s A SHA1 collision is similar to a person “copying” another person’s fingerprints, then using the copied fingerprints to gain access to areas or files that require biometric data. In the case of a SHA1 collision, HTTPS websites that use SHA1 certificates will be vulnerable to attacks that duplicate a specific digital data’s SHA1 hash value.
