This online hash generator converts your sensitive data like passwords to a SHA-1 hash. To calculate a checksum of a file, you can use the upload feature. For further security of the encryption process you can define a HMAC key.

Walkthrough: Encrypting and Decrypting Strings in Visual Basic. 07/20/2015; 3 minutes to read +5; In this article. This walkthrough shows you how to use the DESCryptoServiceProvider class to encrypt and decrypt strings using the cryptographic service provider (CSP) version of the Triple Data Encryption Standard algorithm. Hash function: SHA-1, SHA-256, SHA-384, SHA-512. A hash function maps data of arbitrary size to hash values, hash codes, digests, or simply hashes of fixed size. Usage examples are hash tables, checksums, check digits, fingerprints, lossy compression and randomization functions. Hex to Base32 Atbash latin Trifid cipher The functions crypt() and gen_salt() are specifically designed for hashing passwords.crypt() does the hashing and gen_salt() prepares algorithm parameters for it. The algorithms in crypt() differ from the usual MD5 or SHA1 hashing algorithms in the following respects: An SHA1 hash of the random prefix and data is appended. All this is encrypted with the session key and placed in the data packet.

About the complexity of sha1, sha1 generates a code a different code each 1,4615016373309029182036848327163e+48 (2 ^ 160 bits). So the chances of the use of the same hash is really small. The "problem" of sha1 (and md5) is the speed of the generation. However, the speed is proportional with the length of the text to encrypt. A Very Popular Hashing Function Sha1 Is No Longer Safe to Use. SHA-1 or ‘Secure Hash Algorithm 1’ is a cryptographic hash function that has been used by certificate authorities to sign SSL certificates. The CA/B Forum has announced the deprecation of the SHA-1 algorithm in favor of the newer and more secure SHA-2 hashing algorithms. CryptoJS also supports SHA-224 and SHA-384, which are largely identical but truncated versions of SHA-256 and SHA-512 respectively. SHA-3. SHA-3 is the winner of a five-year competition to select a new cryptographic hash algorithm where 64 competing designs were evaluated. The following cryptographic algorithms are supported: Data Encryption Standard (DES), Triple DES (3DES, 2-key and 3-key) Advanced Encryption Standard (AES) MD5, MD4, and SHA-1 cryptographic hashes. MD5 and SHA-1 Message Authentication Code (MAC) Block cipher modifiers are also provided with DBMS_CRYPTO.

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.
