#Help Joe Bloggs with his password hash#

Joe was confidently using "password1" as his main password to all his accounts until one day he received an e-mail from fBay. His account has been compromised and he must change his password immediately. Yet worse, the attacker had access to all Joe's accounts. Being an engineer, Joe thought: What if I could hash somehow my password using a keyword? I wouldn't need to remember any passwords and I would have a different one for each account.

Joe then creates an algorithm - he takes the domain name as a key and creates the password for each of his account consisting of:

1. (<consonants><vowels>)(alternating case: lower, capital, lower...)
2. <number of consonants><number of vowels>
3. <sum of consonants and vowels numbers converted to a character on US Qwerty Keyboard>

Joe then opens an account on SO to create a new code golf challenge. He uses stackoverflow as a key to generate password:

1. sTcKvRfLwAoEo - consonants and vowels in alternating case
2. 94 - 9 consonants, 4 vowels
3. 9+4=13, 1+3=4, Shift+4=$

Therefore, Joe's password for stackoverflow is: sTcKvRfLwAoEo94$

Challenge

Create a shortest function to generate a password given the rules above. The code should accept a string type parameter d and return/display the generated password.

Rules

1. Only Latin letters from the input should be used. Any other characters should be ignored.
2. Minimum input length is 1 letter. (guys at q.com need passwords as well!)
3. Assume Y is a vowel
4. If vowels or consonants are missing, use 0 accordingly. E.g. input a would result in a01!
5. Shortest code wins

List of vowels and consonants
