Frequently Asked Questions

SHA512 is currently one of the most secure hashing algorithms available. Its 512-bit length makes it virtually immune to collision attacks and extremely resistant to brute-force attempts with modern hardware.

On 64-bit processors, SHA512 can actually be faster than SHA256 because it processes data in 64-bit blocks. This makes it both more secure and highly efficient for modern desktop and server hardware.

A SHA512 hash produces a 512-bit result. In its hexadecimal string representation, it will always be exactly 128 characters long, regardless of whether the input is a single letter or a book.
