Millions of Web users could be left unable to access websites over the HTTPS protocol if those websites only use digital certificates signed with the SHA-2 hashing algorithm. The warning comes from ...

Things are about to get a lot safer on the internet with SHA-2, but there is plenty of work still to be done when it comes to SHA-1 deprecation. For the past couple of years, browser makers have raced ...

The Tuesday updates for Internet Explorer and Microsoft Edge force those browsers to flag SSL/TLS certificates signed with the aging SHA-1 hashing function as insecure. The move follows similar ...

Google this week announced that Shell Hashing Algorithm-1 (SHA-1) has been broken. SHA-1 is a 20-year-old cryptographic approach that's long been used to protect Web traffic. Its use was officially ...

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 Tuesday updates for Internet Explorer and Microsoft Edge force those browsers to flag SSL/TLS certificates signed with the aging SHA-1 hashing function as insecure. The move follows similar ...

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 ...

Researchers claim the "SHAttered attack" can be used to break anything that still uses the legacy SHA-1 cryptographic hash function. (Logo: Shattered.io) The Secure Hash Algorithm-1 - aka SHA-1 - ...

In February 2017, Google and CWI announced they had broken SHA-1 encryption. This isn't a surprise: The encryption, used for things like digital signatures, had been susceptible to collisions for ...
