subject: Allow Microsoft HMAC-MD5 checksum types to use non-RC4 keys
target_version: 1.8.3
tags: pullup
In PAC signatures, the hmac-md5 checksum type can be used with AES
keys. Make this work by removing the enc field from the hmac-md5 and
md5-hmac checksum types, and adding a check in
krb5int_hmacmd5_checksum() for a null key or a key which is longer
than the hash block size (64 bytes for MD5). The checksum algorithm
only uses the key bits; it does invoke the cipher.
The checksum type names are kind of wrong, but we'll leave them alone
for compatibility. The descriptions are updated.
