You need to remember this string as the only way to decode the SHA-256 hash is by using the original text.Since its introduction, this Perfect Passwords page has generated a great deal of interest. There are many other applications that use SHA-256 for encryption, network security, and data transfer, including SSL/TLS, SSH, and Internet protocol security.Įnter any string to be decoded to an SHA-256 hash. In blockchain applications, the previous hash value is used to calculate the hash value of the current block which makes it almost impossible to crack. In fact, SHA-256 is used for Bitcoin mining and many population blockchain applications. SHA-256 is a very secure hash algorithm for authentication and data protection.

Whereas the lowercase of the same string 'hello world' gives the following SHA-256 hash.ī94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9.

To demonstrate, let's take a look at an SHA-256 example. If there is even one character difference in the original string or a change in any character from lowercase to uppercase, the SHA-256 encoded string would look completely different. The encoded string is not crackable unless the original string is known. The converted hash has 64 hexadecimal characters, equivalent to 256 bits, which is why it is called the secure hash algorithm 256 or SHA-256 hash. SHA256 is a hash algorithm to encode one string to a more secure string, called hashing. For extra security, users can use our password generator to generate a strong password, and then use the SHA256 hash to encode that password. The SHA256 password generator will generate a password that is hard to crack.
