Generate cryptographic hashes for text or files to verify data integrity and security. Supports MD5, SHA-1, SHA-256, SHA-384, and SHA-512 algorithms.
Verify file integrity by comparing hash values before and after file transfer or storage.
Ensure downloaded files haven't been tampered with by comparing their hash with the official hash.
Even a small change in the input produces a completely different hash output, making it ideal for detecting changes.
Hash functions are essential cryptographic tools that convert data of any size into a fixed-size string of characters. They are designed to be one-way functions, meaning it's practically impossible to reverse the process and obtain the original data from the hash.
SHA-256: Part of the SHA-2 family, it produces a 256-bit (32-byte) hash value. It's widely used for data integrity verification and is considered secure for most applications.
SHA-512: Produces a 512-bit hash value, offering even greater security than SHA-256. Recommended for highly sensitive applications.
MD5: Produces a 128-bit hash value. It's no longer considered secure for cryptographic purposes due to vulnerabilities, but is still used for checksums and data verification.
SHA-1: Produces a 160-bit hash value. Like MD5, it's no longer considered secure for cryptographic purposes but is still used in some legacy systems.
Data Integrity: Verify that files haven't been corrupted during transfer or storage by comparing hash values.
Password Storage: Securely store password hashes instead of plaintext passwords in databases.
Digital Signatures: Verify the authenticity and integrity of digital documents and software.
Blockchain Technology: Hash functions are fundamental to blockchain technology and cryptocurrencies.
Data Deduplication: Identify duplicate data by comparing hash values instead of the entire content.
