Use this tool to quickly calculate SHA1, SHA256, SHA384 and SHA512 hashes.
SHA-1, SHA-256, SHA-384, and SHA-512 are cryptographic hash functions that belong to the Secure Hash Algorithm (SHA) family. They are widely used for data integrity, digital signatures, and other cryptographic applications.
SHA-1 (Secure Hash Algorithm 1) produces a 160-bit hash value and operates on 512-bit blocks. However, due to security vulnerabilities, including collision attacks, it is considered weak and no longer recommended for secure applications.
SHA-256 (Secure Hash Algorithm 256-bit) is a widely used variant of SHA-2. It generates a 256-bit hash value and operates on 512-bit blocks. It offers significantly stronger security than SHA-1 and is considered secure for most applications.
SHA-384 and SHA-512 are both members of the SHA-2 family and provide even stronger security. SHA-384 generates a 384-bit hash value, while SHA-512 produces a 512-bit hash value. They operate on 1024-bit blocks, making them slower but more secure than SHA-256.
These SHA algorithms are designed to provide integrity and security, with longer hash lengths offering increased resistance against collision and pre-image attacks. SHA-256, SHA-384, and SHA-512 are widely recommended for cryptographic purposes today and are used in various applications, including digital signatures, password storage, and data integrity verification.
