The SHA-1, SHA-256 and MD5 algorithms are three of the most common cryptographic hash functions in use today. They are typically used in message authentication and digital signature applications, where a message or file requires tamper protection or origin authentication. The Helion Fast Hashing cores have been designed to implement SHA-1, SHA-256 and MD5 in Xilinx technology for high throughput applications. Single-mode versions are available which are suitable where support is only required for one of these algorithms. Two dual-mode versions are also available, sharing common resources to offer selectable support for both SHA-1 and MD5, or SHA-1 and SHA-256, whilst using fewer logic resources than two individual solutions. These solutions are well proven in real products, extremely easy to use, and very efficiently implemented in any Xilinx technology.
