Full cryptography playlist :    • Cryptography ( Encryption ) and its types ...  
These video mentions important concepts of Hash (and also other sections of cryptography). What is a collision ? What is preimage resistance ? What is second preimage resistance ? What are preimage and second preimage attacks ? How collision differs from second preimage attacks. Is sha-1 really broken ? Is MD5 really broken ? Is there any known preimage or second preimage attack against known hash like MD5 or SHA-1 or others. Why you should not use these hash for passwords. Can you use SHA-1 for passwords hashing in your website. How was shatter attack actually done. What is chosen prefix attack collision attack. Many such questions answered in this video. Very important video when cryptography is concerned.
