org.apache.directory.shared.kerberos.components.EncryptionKey.computeLength()

Compute the EncryptionKey length

 EncryptionKey : 0x30 L1 EncryptionKey | +--> 0xA0 L2 keyType tag |     | |     +--> 0x02 L2-1 keyType (int) | +--> 0xA1 L3 keyValue tag | +--> 0x04 L3-1 keyValue (OCTET STRING) where L1 = L2 + lenght(0xA0) + length(L2) + L3 + lenght(0xA1) + length(L3)  and L2 = L2-1 + length(0x02) + length( L2-1)  L3 = L3-1 + length(0x04) + length( L3-1)
