SHA-1
Features
- Suitable for data authentication applications
- Fully synchronous design
- Available in VHDL or Verilog
Description
This megafunction is a fully compliant implementation of the secure hash algorithm (SHA-1). It computes a 160-bit message digest for messages up to (216- 1) bits.
Developed for easy reuse in ASIC and FPGA applications, the SHA-1 is available optimized for several technologies with competitive utilization and performance characteristics.
