About the technology
What cryptography covers
Cryptography protects information while it is stored, transmitted and processed. It uses mathematical techniques to provide confidentiality, integrity, authentication and non-repudiation. Specialists turn these principles into reliable controls for applications, devices, networks and business processes.
Security building blocks
Modern cryptographic work spans symmetric encryption, asymmetric encryption, hashing, digital signatures and secure random number generation. It also includes certificate chains, cryptographic protocols, key derivation and secrets handling. Strong implementations select established primitives and apply them correctly rather than inventing new algorithms.
Ecosystem and tooling
Professionals work across standards, libraries and hardware-backed security components. Common technologies include TLS, OpenSSL, BoringSSL, libsodium, Java Cryptography Architecture, .NET cryptographic APIs and hardware security modules. They may also assess PKI, OAuth, FIDO2, secure boot and cloud key management services.
Where companies use it
Cryptography appears in products and systems that must establish trust or protect sensitive data:
- Encrypting customer, payment and health information
- Securing APIs, messaging systems and service-to-service traffic
- Issuing certificates and signing software or documents
- Protecting connected devices, firmware and industrial networks
- Supporting identity, access control and zero-trust designs
When specialist support helps
Companies bring in freelance expertise when an application needs a new security design, an audit reveals weaknesses or a legacy implementation must be replaced safely. In Germany, specialists may support regulated industries, manufacturing, automotive, finance and public services while coordinating with internal security, legal and infrastructure teams. Remote delivery is common, with on-site collaboration useful for sensitive environments and hardware work.
What strong professionals deliver
The best specialists connect theory with careful engineering. They define threat models, choose suitable standards, document trust boundaries and test failure cases. They understand side-channel risks, nonce reuse, certificate renewal, key rotation and secure deployment. Clear explanations matter because cryptographic controls must remain usable for product and operations teams.
Frequently asked questions
What clients ask us most about Cryptography — answered in short.
Cryptography is used to protect data, verify identities and prove that messages or files have not been changed. Companies apply it to encrypted storage, secure network connections, digital signatures, authentication, payments and connected devices.
Cryptography is the broader discipline behind secure communication and data protection. Encryption is one part of it; hashing, digital signatures, key exchange and authentication mechanisms are other important parts.
A strong Cryptography specialist often understands application security, network protocols, identity and access management, cloud security and secure software development. Experience with threat modeling, incident response and compliance can also help connect technical controls to business risks.
The right depth depends on the risk and scope of the work. A specialist integrating established libraries needs strong implementation discipline, while protocol design, formal review, hardware security or post-quantum planning calls for advanced cryptographic knowledge and a record of reviewing complex systems.
Cryptography projects can often be delivered remotely through secure repositories, documented threat models and controlled access to test environments. On-site work may be preferable when the scope includes hardware security modules, secure facilities or direct collaboration with teams handling highly sensitive systems in Germany.
Cryptography is appropriate when a company must protect information, establish trust or detect tampering. It does not replace access controls, secure coding, monitoring or governance, so the solution should combine cryptographic protections with the wider security architecture.
Look for clear threat assumptions, documented design decisions and careful use of established standards and libraries. Good Cryptography work explains key ownership, rotation, recovery, failure handling and testing, and it avoids custom algorithms unless there is a compelling, independently reviewed reason.
A Cryptography professional needs patience with documentation, reviews and precise security requirements. Projects may involve legacy systems, restricted environments and coordination across product, infrastructure and compliance teams, so communication and disciplined change control are as important as mathematical knowledge.
The average hourly rate of freelancers in Germany who have used Cryptography in their recent projects is 109 €, which corresponds to a daily rate of about 874 € based on an 8-hour working day.
