SSH, or Secure Shell, is a cryptographic network protocol for secure and encrypted communication over unsecured networks. It is significant for its ability to provide secure remote access to servers, secure file transfer, and a reliable means of executing remote commands, all while ensuring the confidentiality and integrity of data in transit.

A phylogenetic tree is a branching diagram that shows the evolutionary relationships among different species or entities, based on their physical or genetic characteristics. It illustrates how species have diverged from common ancestors over time. These trees are constructed using morphological or genetic data and are used in biology, epidemiology, and conservation to understand the evolutionary history and relationships of organisms.

CD-HIT was originally a protein clustering program. The main advantage of this program is its ultra-fast speed. It can be hundreds of times faster than other clustering programs, for example, BLASTCLUST. Therefore it can handle very large databases, like NR. The 1st version of this program, CD-HI, was published and released in 2001. The 2nd version, called CD-HIT, was published in 2002 with significant improvements. Since 2004, CD-HIT has been hosted at bioinformatics.org as an open source project. Current CD-HIT package can perform various jobs like clustering a protein database, clustering a DNA/RNA database, comparing two databases (protein or DNA/RNA), generating protein families, and many others.
