WebCommon types of non-cryptographic hash functions: Perfect Hash Functions map each valid input to a different hash value. The output space must be larger than the input space. This does not imply collision resistance as the property is defined based on the input space. WebIrreversible: Unlike encryption, Cryptographic Hash Functions are one-way. Once encrypted, you can never decrypt them even if you have the exact hashing algorithm that was used for the encryption. Simply put, there is no decryption in CHFs. Hence, they are irreversible.
