The Department of Defense requires information assurance specialists and cybersecurity service providers to obtain specific certifications known as Information Assurance Baseline Certifications.

These certificates are necessary for accessing DoD Web sites, but most Web browsers do not include DoD Class 3 and ID Root CAs as trusted roots, leading to warning messages when trying to access these websites.


SHA-1 was developed by the National Security Agency and produces message digests similar to those created by Ronald L. Rivest of MIT for his MD2, MD4 and MD5 message-digest algorithms; however, its larger hash size and block size make it more resistant against brute force attacks; additionally it uses multiple rounds of hashing, making collision detection harder for attackers. Although still used today in some areas, its weaknesses are becoming apparent as computing power increases along with advances in cryptanalysis techniques.

Provide your users with a safe experience on your website by installing certificates that authenticate identities, secure transactions and sign documents reassuring readers that it came directly from you. Digital signatures also offer more secure ways of signing documents than wet ink signatures do.

DoD-approved Certificate Authorities offer many certificate options; those issued by DoD CAs are of particular significance in that their subscriptions are seen by DoD PKI subscribers as trusted. Their root CA public key serves to validate all certificates issued. They are overseen by a CAC Authority Board which reviews them regularly to ensure their security practices comply with DoD standards.

DoD recommends SHA-2 certificates with 2048-bit keys as the optimal way of protecting networks and systems, which is more secure than its predecessor SHA-1 and has longer block sizes, making it harder for hackers to locate collisions. However, some risks exist with using SHA-2 in terms of being vulnerable to certain forms of attacks as well as its slow performance; so for optimal protection it may be beneficial to utilize stronger hashing algorithms such as SHA-256 instead.

DoD certification requirements can be found in DoD directive 8570 and 8140, which stipulate information assurance specialists, cybersecurity service providers and other technical professionals to maintain certifications that demonstrate their knowledge of DoD systems. Those seeking to meet these requirements can enroll in online certification courses that prepare them for exams such as Certified Information Security Specialist (CISSP), CompTIA A+ or CCNA Security exams.


SHA-2 stands for Secure Hash Algorithm and is now the standard SSL Certificate algorithm. SHA-2’s mathematics don’t share those of its predecessor, SHA-1; therefore it is far harder for collisions (when two pieces of data produce identical hash values) to occur compared with its predecessor – this upgrade protects your privacy while guaranteeing that websites you visit don’t misrepresent themselves as others. This upgrade will help safeguard your privacy by guaranteeing they do not impersonate other sites when browsing online.

The Department of Defense (DoD) imposes several requirements on individuals working with its information systems, as outlined by Directives 8570 and 8140. Information assurance specialists and cybersecurity service providers must obtain certain certifications that verify they understand various technologies as well as troubleshooting problems; some popular certifications include CompTIA A+, CCNA Security, and SSCP exams; numerous online courses can help prepare professionals for these exams.

ECA certificates are used to authenticate users and verify their credentials when accessing DoD information systems, while also enabling DoD entities and users to communicate securely among themselves and protect confidential e-mail communications.

Since 2008, the Department of Defense’s External Certification Authority Program has been operational. Through this initiative, DoD funds a public key infrastructure (PKI) to issue certificates to industry partners and other external entities. Authenticate users before issuing them certificates that grant access to secure DoD information systems.

While switching to SHA-2 may be a positive step towards improving DoD cybersecurity, it should be remembered that it’s just the first step of an ongoing journey. Threat landscapes change frequently so it’s crucial that security practices continue being assessed and evaluated. Furthermore, staying abreast of new advancements within cryptographic hash functions will equip you better to deal with any emerging threats in the future.


SHA-3 is the third in a series of hash functions developed by the National Institute of Standards and Technology (NIST). Designed as a replacement for earlier techniques like SHA-1 and SHA-2, this hash function offers improved security benefits while simultaneously supporting more applications than its predecessors.

SHA-3 includes four fixed-size hash functions SHA3-224, SHA3-256, SHA3-384 and SHA3-512 that can achieve 128-bit or 256-bit security levels if input length allows; additionally two extendable output hash functions (SHAKE128 and SHAKE256) offer extendable output capabilities and may reach 128-bit or 256-bit security levels depending on input length requirements. Unlike their SHA-1 and SHA-2 counterparts, these hash functions have different designs to enhance preimage resistance and help them achieve higher security levels without incurring further preimage attacks.

SHA-3 protocol implementation uses application-specific integrated circuit (ASIC) or field programmable gate array (FPGA), both of which provide superior power, speed, and throughput performance compared to software-based solutions. ASIC/FPGA also provide greater levels of flexibility than software solutions since designers can select how many rounds and hashing operations per clock at design time.

Though SHA-3 provides enhanced security, its slower software performance makes it less attractive for miners compared to its counterparts SHA-1 and SHA-2; this has delayed its migration; however as attacks against SHA-2 continue to escalate it will eventually become inevitable and we will move toward it more and more quickly.

ASIC and FPGA implementations of SHA-3 offer higher reliability than software-based solutions, which is particularly important in embedded systems where failure of cryptographic algorithms could have dire repercussions. As a result, ASIC/FPGA-based SHA-3 IP core is expected to play an essential part in future Internet of Things (IoT) designs as well as embedded communications designs.

NIST held its SHA-3 competition between 2008 and 2012 and ultimately selected Keccak as its winning entry as the basis of the final standard, sparking much criticism due to changes that deviated from what had been promised during competition. NIST modified Keccak is not a direct successor of original winner Keccak; therefore its modifications may be driven by wanting greater preimage resistance – the primary goal of SHA-3 standards.


SHA-4 is a security protocol created for use by organizations requiring advanced cryptographic features. Among its key advantages are support for an increased number of cryptographic operations, improved efficiency and handling larger amounts of data than previous versions of this protocol. Furthermore, it uses encryption using asymmetric algorithms while offering stronger protection from adaptive adversaries than its predecessor. Furthermore, compatibility with existing PKI infrastructures ensures no changes are necessary on servers or browsers for using it.

Professionals working for the Department of Defense require information assurance certification in order to comply with specific certification requirements based on their role and level of access. These regulations can be found in DoD Directives 8570 and 8140 which include lists of approved certification providers.

The DoD root certificate is a self-signed digital certificate that authenticates itself, signing certificates issued by its subordinate CAs, and acting as the trust anchor for DoD PKI subscribers to verify all certificates that start with it and their paths starting there. Unfortunately, due to containing confidential and private information it cannot be accessed over the internet.

An ECA Certificate from DoD can help to secure your website by signing documents and emails with its digital signature, authenticating recipients, or both. It’s especially helpful for organizations needing to secure remote connections or mobile devices.

DoD ECA certificates offer businesses more than security; they’re an effective way to increase customer trust. Users can easily identify the business behind a website while developing trust between themselves and that website. In addition, digital signatures provide reliable, secure, legally-binding processes which replace wet ink signatures with reliable signature verification processes that users trust.

An information assurance certificate can help you advance in cybersecurity, opening up many different career possibilities. From taking individual courses to learn the fundamentals to master’s programs in cyber security – both options offer invaluable credentials that will boost your resume and open up new career paths.
