SHA1 Hash calculator

This program helps you determine the integrity of your data and challenge hash authentication.

Enter Value


An SHA-1 Hash calculator is a tool that creates a 160-bit (20-byte) hash value for a specified input, generally referred to as a "message" or "data." It processes the input using the SHA-1 algorithm, a cryptographic hash function, to generate a unique hash value that may be used to validate the input's integrity.

What is SHA1 Hash?

HA 1 stands for Secure Hash Algorithm 1. It uses a cryptographic hash algorithm to 160-bit (20 bytes) Hash value. It is commonly used to verify data integrity, such as messages and files, by giving the data a special "hash" value. The hash value will alter if the data is changed in any way.

How does SHA1 Hash Work?

The SHA-1 algorithm applies several mathematical operations, such as bitwise operations and modular arithmetic, on input (or "message"). The algorithm's output is a fixed-size, 160-bit (20-byte) hash value specific to the input message.

Use Cases of SHA1 Hash in Software Testing:

  • Software Testing: During software testing, it is necessary to verify whether the output we are receiving is correct or not Comparing the output to a known "good" output is one technique to accomplish this. Making an SHA-1 Hash of the known output and comparing it to the SHA-1 Hash of the actual output is a popular method. The output is likely accurate if the two hashes match.

  • File Verifications: During software development and deployment, it is necessary to check out that file that gets distributed is similar to the original and hasn't been tempered. To maintain this authenticity, you can make a copy of the original file's SHA-1 hash and send it along with the distributed file.

  • Data Integrity: While transmitting data from one place to another, it's necessary to check that it remains original and hasn't been modified. Data can be encrypted with SHA1 and can be delivered or saved with the data. If two hashes match, then it shows that the data has not been altered.

How to Use LambdaTest SHA1 HASH Calculator:

LambdaTest SHA1 HASH calculator uses to convert your data into SHA1 Hash. You can follow the steps given below:

  • There is an input field where you can add your data of any size which you want to convert into SHA1 Hash.
  • Press the “Calculator SHA1” button.
  • You will receive the SHA1 version of your entered data, which is a 160-bit message digest. This message digest is often represented as a 40-digit hexadecimal number.
  • This tool is free, so you can use it multiple times for any size of data.

What is SHA1 Hash Calculator?

SHA1 Hash Calculator allows you to generate the SHA1 hash from any string. It is more secure than MD5. You can use the online tool to generate the SHA1 checksum of your files to verify their identity later or generate the SHA1 hashes of your users' passwords to prevent your users' passwords from being leaked.

How does SHA1 Hash Calculator work?

The SHA1 online hash generator converts your sensitive data into an SHA1 hash. SHA-1 or Secure Hash Algorithm 1 takes an input of any length and produces a 160-bit message digest. This message digest is usually rendered as a hexadecimal number which is 40 digits long.

Can SHA-1 Hash be decrypted?

It is impossible to decrypt SHA1 Hash. It is one way Hash function, so it can’t be reversed once it’s encrypted.

How is the SHA-1 Hash calculated?

When a message is fed to SHA-1 as a bit string less than 2^64 bits, it produces a 160-bit hash value called a message digest. For compactness, the message below is displayed using hexadecimal notation.
