Cryptographic hash functions are widely used in many aspects of security, such as digital signatures and data integrity checks. The short digital fingerprint generated from an electronic file, message ...
This is an explanation of the Cryptography problem "It is my Birthday 2" from CyLab Security Academy (formerly picoCTF). You are provided with one file, invite.pdf. There is a form on the webpage to ...
The SHA1 (Secure Hash Algorithm 1) cryptographic hash function is now officially dead and useless, after Google announced today the first ever successful collision attack. SHA1 is a cryptographic hash ...
For more than six years, the SHA1 cryptographic hash function underpinning Internet security has been at death’s door. Now it’s officially dead, thanks to the submission of the first known instance of ...
If you thought MD5 was banished from HTTPS encryption, you’d be wrong. It turns out the fatally weak cryptographic hash function, along with its only slightly stronger SHA1 cousin, are still widely ...
