cas.ticket.registry.memcached.hashAlgorithm=FNV1_64_HASH
cas.ticket.registry.memcached.protocol=BINARY

cas.ticket.registry.memcached.crypto.signing.keySize=512
cas.ticket.registry.memcached.crypto.encryption.key=
cas.ticket.registry.memcached.crypto.encryption.keySize=256
cas.ticket.registry.memcached.crypto.alg=AES

#ticket settings
cas.ticket.st.maxLength=20
cas.ticket.st.numberOfUses=1
