Examples of -collision proof checksums are MD5, and SHA1, while CRC32 is not. -.Pp -.Fn krb5_checksum_is_keyed -returns true if the specified checksum type is keyed (that the hash -value is a function of both the data, and a separate key). Examples of -keyed hash algorithms are HMAC-SHA1-DES3, and RSA-MD5-DES.
