What is sha1 (SHA-1)?
The Secure Hash Algorithm 1, also known as SHA-1, is a cryptographic hash function that generates a 160-bit (20-byte) hash value from input data. This hash value typically represents a 40-digit hexadecimal number. The primary use of SHA-1 is to verify the integrity of a file by calculating a checksum before and after transmission to ensure that the file is not altered during the transfer process. Use our free SHA1 online Hash Generator tool to generate the SHA1 hash password for a given word or text.
It’s important to note that SHA-1 is not encryption, but rather a unique identifier for the input data. Additionally, since it’s a one-way transaction, it’s nearly impossible to reverse the SHA-1 hash to retrieve the original data. The resulting SHA-1 hash is a 40-character hexadecimal string.
