Online Hash Calculator. Online Hash Calculator lets you calculate the cryptographic hash value of a string or file. Multiple hashing algorithms are supported including MD5, SHA1, SHA2, CRC32 and many other algorithms.

string sha1 ( string $str ) Calculates the sha1 hash of str using the US Secure Hash Algorithm 1, and returns that hash. Today, many applications still rely on SHA-1, even though theoretical attacks have been known since 2005, and SHA-1 was officially deprecated by NIST in 2011. We hope our practical attack on SHA-1 will increase awareness and convince the industry to quickly move to safer alteratives, such as SHA-256. This online tool allows you to generate the SHA256 hash of any string. SHA256 is designed by NSA, it's more reliable than SHA1. Enter your text below: Test and run sha1 online in your browser. Calculates the sha1 hash of $str using the « US Secure Hash Algorithm 1 ». What does MD5 mean? MD5 is the abbreviation of 'Message-Digest algorithm 5'. The MD5 algorithm is used as an encryption or fingerprint function for a file.

Online HMAC hash generator: HMAC-MD5, HMAC-SHA. A keyed-hash message authentication code (HMAC) uses a cryptographic hash function (MD5, SHA-1, SHA-512 …) and a secret cryptographic key to verify both the data integrity and the authentication of a message.

SHA1 Hash. Online tool for creating SHA1 hash of a string. Generate SHA1 message digest from an arbitrary string using this free online SHA1 hash utility. SHA1 online hash function Input type Description: SHA1 is relatively similar to MD5 but more secure, and is slowly replacing MD5 as the "common" hashing algorithm for password digests (along with the SHA2 group) Full list of hashing, encryption, and other conversions

This online tool allows you to generate the SHA256 hash of any string. SHA256 is designed by NSA, it's more reliable than SHA1. Enter your text below:

This website uses a SHA-1 reverse dictionary containing several millions of entries, which you can use with SHA-1 hashes from your application. If some of the hashes you enter can be reversed, consider using another way of generating hashes, like using stronger algorithms ( SHA-2 , Whirlpool , etc), combining algorithms, and using a " salt ". SHA-1 (160 bit) is a cryptographic hash function designed by the United States National Security Agency and published by the United States NIST as a U.S. Federal Information Processing Standard. SHA-1 produces a 160-bit (20-byte) hash value. A SHA-1 hash value is typically expressed as a hexadecimal number, 40 digits long.
