Tech Specs


Certified Hardware Solutions

Entrust has earned a broad set of certifications for nShield products. These certifications help our customers to demonstrate compliance while also giving them the assurance that their nShield HSMs meet stringent industry standards.

Safety and Environmental Standards Compliance

  • UL, CE, FCC, RCM, Canada ICES
  • RoHS2, WEEE

Security Compliance

  • eIDAS and Common Criteria EAL4 + AVA_VAN.5 and ALC_FLR.2 certification against EN 419 221-5 Protection Profile, under the Dutch NSCIB scheme
  • Can form the basis of an EN 419 241-2 certified remote signing system for eIDAS
  • Compliant with BSI AIS 31 for true and deterministic random number generation
  • ICP Brazil certification to NSC3 level
  • Singapore CSA NITES certification for nShield Solo XC models

Supported APIs

  • PKCS#11, OpenSSL, Java (JCE), Microsoft CAPI and CNG

Supported Cryptographic Algorithms

  • Asymmetric public key algorithms: RSA, Diffie-Hellman, ECMQV, DSA, KCDSA, ECDSA, ECDH, Edwards (X25519, Ed25519ph)
  • Symmetric algorithms: AES, AES-GCM, ARIA, Camellia, CAST, RIPEMD160 HMAC, SEED, Triple DES
  • Hash/message digest: SHA-1, SHA-2 (224, 256, 384, 512 bit), HAS-160
  • Full Suite B implementation with fully licensed ECC, including Brainpool and custom curves
  • Elliptic Curve Key Agreement (ECKA) available via Java API and nCore APIs
  • Elliptic Curve Integrated Encryption Scheme (ECIES) available via Java API, PKCS#11 and nCore APIs

nShield HSMs offers the majority of these cryptographic algorithms as part of the standard feature set. For organizations wishing to use ECC or South Korean algorithms, optional activation licenses are needed.

Supported Platforms

Windows and Linux operating systems including distributions from RedHat, SUSE and major cloud service providers running as virtual machines or in containers.

Solo XC virtual environments supported including VMware ESX, Microsoft Hyper-V, Linux KVM & Citrix XenServer

High Transaction Rates

nShield HSMs boast high elliptic curve cryptography (ECC) and RSA transaction rates. ECC, one of the most efficient cryptographic algorithms, is particularly favored where low power consumption is crucial, such as applications running on small sensors or mobile devices.

nShield Monitor

nShield Monitor is a monitoring platform that provides 24x7 visibility into the status of payShield and nShield HSMs. With this solution, security teams can efficiently inspect HSMs and find out immediately if any potential security, configuration or utilization issue may compromise their mission-critical infrastructure.

Remote Administration Kits

nShield Remote Administration lets operators manage distributed nShield HSMs – including adding applications, upgrading firmware, checking status, re-booting and more – from their office locations, reducing travel and saving money. Remote Administration Kits contain the hardware and software needed to set up and use the tool. These kits are available for nShield Solo and nShield Connect HSMs.


CodeSafe is a powerful, secure environment that lets you execute applications within the secure boundaries of nShield HSMs. Sample applications include digital meters, authentication agents, digital signature agents and custom encryption processes. CodeSafe is available with FIPS Level 3 certified network attached and PCIe nShield HSMs.


CipherTools is a set of tutorials, reference documentation, sample programs and additional libraries. With this toolkit, developers can take full advantage of the advanced integration capabilities of nShield HSMs. In addition to offering support for standard APIs, the toolkit enables you to run custom applications with nShield HSMs. CipherTools is included free of charge in the standard Security World software ISO/DVD.

Elliptic Curve Cryptography (ECC) Activation

The ECC activation license enables EC-DH, EC-DSA and EC-MQV to be used on an nShield HSMs.

KCDSA Activation

With the KCDSA activation license, you can use the Korean Certificate-based Digital Signature Algorithm (KCSDA) as well as HAS-160, SEED and ARIA algorithms on an nShield HSMs.

Smart Card Reader Rackmount

For organizations deploying one or more nShield Solo modules in a 19" rack, the optional nShield smart card reader rackmount provides a practical and clean solution for attaching card readers in the data center. The rackmount is 1U in height and can be equipped with up to four smart card readers, which come standard with nShield Solo cards. Each unit is packaged with three blanking plates to cover any unused slots.
