We are not responsible for any loss of data or personal information. SHA-1 hash values are used at the user's own risk and no liability will be assumed.
SHA-1 is the most widely used of the existing SHA hash functions, and is employed in several widely used security applications and protocols. The message digest produced by SHA-1 generator is also non-reversible and uniquely identifies the data. Our free SHA-1 hash tool uses encryption algorithm which is also known for its difficult computation. It is hard to find a message that corresponds to a given SHA-1 digest or two messages that produces that same digest. Any change in the message will make it difficult to verify.
