WebMar 8, 2024 · SHA-512 and the other SHA2 variants (SHA-256, SHA-384, etc.) have collisions. We know this by applying a very simple mathematical theorem, the pigeonhole principle. A SHA-512 hash is a 64-byte string. There are strictly more strings of 0 through 64 bytes than strings of exactly 64 bytes. WebMay 14, 2024 · 1 Answer Sorted by: 8 SHA-256 and SHA-512 produce 256 and 512 bit hashes, respectively. Your RSA key is 1024 or 2048 bits, and the block size when using it as a cipher is the same. Since both hashes are smaller than the RSA block size, they need to be padded out to that size.
