Is SHA1 reversable?
We can't reverse or decode the SHA1 hash key. That is why its called Secure Hash Algorithm. SHA-1 is a hash function that was created to make reversing the process extremely difficult. Because of this, such hash functions are typically known as one-way functions or cryptographic hash functions.
Definition / Uses
SHA1 stands for "Secure Hash Algorithm 1", SHA1 is a cryptographic function, which transforms a string into a 160 bit hash value. This hash value is typically presented as a hexadecimal number. The generated key contains 40 digits. Online SHA1 Hash Key Generator is much similar to MD5 generator which is useful for encoding passwords, credit card numbers, and many more sensitive data into MySQL or similar. But the SHA1 hash key is more secure and faster than the MD5 key generator. It is an online tool that allows you to create a SHA1 hash key by using a string. You can generate the SHA1 checksum of your files to verify the identity of them later or generate the SHA1 hashes of your sensitive data like user passwords to prevent them from being leaked. SHA1 is like fingerprints of a data set.
How to generate Hash key by using SHA1 Hash Key Generator tool?
SHA1 key generator is a user-friendly tool. Here are the following basic steps to use our SHA1 hash key generating tool.
- Enter a string to generate a SHA1 hash key generator tool.
- Press the “Generate” button to generate the hash key for the string.
- Press the “Copy” button to copy the generated hash key.
- Press the “Clear” button to remove the current string and add a new one in it.
Example:
Let's try an example. We have entered a string "SHA1 is an amazing tool" in our SHA1 Hash generator online tool. On pressing the "Generate" button this tool will show 40 digits generated output "aba7f10e30fcf7f96953935462401210c7b205ed" as the generated Hash key.
Is SHA1 a secure tool?
Yes! SHA1 is a 100% secure tool. It's a free online Hash key Generator tool. It allows you to produce a hash key from a string that is more secure than an MD5 generator. As you see in the upper example it converts the simple string value in code language which is impossible to understand. We can't decode OR reverse the generated value, also the generated value is not displayed as publicly on the internet. The only user can see the output. Moreover, it is a free online tool for all users. No sign-up, registration OR captcha is required to use this tool.
