Sha1 — Reverse lookup, unhash, and decrypt. 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. This online SHA256 Hash Generator tool helps you to encrypt one input string into a fixed 256 bits SHA256 String. Paste your Input String or drag text file in the first textbox, then press "SHA256 Encrypt" button, and the result will be displayed in the second textbox. SHA256 and Blockchain Security: SHA-512 Cryptographic Hash Algorithm. A cryptographic hash (sometimes called 'digest') is a kind of 'signature' for a text or a data file. SHA-512 generates an almost-unique 512-bit (32-byte) signature for a text. AES encryption is a web tool to encrypt and decrypt text using AES encryption algorithm. /** * CBC 128 192 256 CBC-HMAC-SHA1 128 256 CBC-HMAC-SHA256 128 256 CFB 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. Ascii85 Text to morse code Text to octal The variety of SHA-2 hashes can lead to a bit of confusion, as websites and authors express them differently. If you see “SHA-2,” “SHA-256” or “SHA-256 bit,” those names are referring to the same thing. If you see “SHA-224,” “SHA-384,” or “SHA-512,” those are referring to the alternate bit-lengths of SHA-2. SHA-256 (256 bit) is part of SHA-2 set of cryptographic hash functions, designed by the U.S. National Security Agency (NSA) and published in 2001 by the NIST as a U.S. Federal Information Processing Standard (FIPS). A hash function is an algorithm that transforms (hashes) an arbitrary set of data elements, such as a text file, into a single

SHA-1 - Wikipedia
The U.S. National Institute of Standards and Technology has banned the use of SHA-1 by U.S. federal agencies since 2010, and digital certificate authorities have not been allowed to issue SHA-1 The primary difference between SHA-1 and SHA-2 is the length of the hash. While SHA-1 is the more basic version of the hash providing a shorter code with fewer possibilities for unique combinations, SHA-2 or SHA-256 creates a longer, and thus more complex, hash. In 2015, new SSL certificates with SHA-1 were phased out. Electronic Codebook (ECB) mode is the simplest encryption mode in Advanced Encryption Standard (AES). AES is a symmetric-key algorithm i.e. same key is used to encrypt and decrypt data. In AES, message is divided into block-size of 128 bits(16 bytes) to perform encryption or decryption operation. AES allows key size of 128, 192 or 256 bits. Nov 23, 2018 · I want to calculate the hasvalue f.e. sha256 from the values and/or the text in a specific cell or range of cells.
