Start compatibility testing now
Identify applications, libraries, devices, and services that can consume ML-DSA keys and certificates before migration becomes time-sensitive.
Post-quantum PKI and cryptographic agility
Prepare your PKI for the post-quantum transition.
NIST standardized ML-DSA in FIPS 204 for post-quantum digital signatures. SecuriTLS supports ML-DSA alongside RSA and elliptic curve cryptography so private PKI teams can begin testing migration paths before quantum-resistant signatures become an urgent requirement.
Create ML-DSA certificate authorities and leaf certificates, build mixed-algorithm hierarchies, and manage lifecycle, revocation, storage, custody, deployment, validation, and audit workflows from the same platform.

Why post-quantum readiness matters
Cryptographic migration takes longer than generating a new key.
NIST says organizations should begin migrating systems to quantum-resistant cryptography. PKI migration requires inventory, compatibility testing, trust-chain design, lifecycle operations, deployment changes, and validation across the systems that consume certificates.
Keep existing algorithms available
RSA and EC remain important for compatibility. Crypto agility means being able to operate multiple algorithms while migration is underway.
Automate the operational layer
A new signature algorithm still needs issuance, renewal, revocation, deployment, validation, storage, custody, and audit workflows.
Supported algorithms
One lifecycle across RSA, EC, and ML-DSA.
RSA
2048, 3072, and 4096-bit keys with SHA-256, SHA-384, and SHA-512 signature hashes.
Elliptic Curve
P-256, P-384, and P-521 keys with supported SHA-2 signature hashes.
ML-DSA
ML-DSA-44, ML-DSA-65, and ML-DSA-87 parameter sets for post-quantum digital signatures.
Migration strategy
Use mixed-algorithm hierarchies to test realistic transition paths.
The subject public-key algorithm and issuer signing algorithm do not have to be the same. SecuriTLS supports mixed-algorithm private PKI paths so you can test how different trust chains behave across your infrastructure.
1
Inventory consumers
Find the services, devices, libraries, and automation that depend on your certificate formats and signature algorithms.
2
Build an ML-DSA test hierarchy
Create post-quantum CAs or leaves alongside RSA and EC and validate application compatibility.
3
Automate rotation and deployment
Treat cryptographic migration as a lifecycle operation rather than a one-time certificate-generation project.
NIST standardization
ML-DSA is standardized in FIPS 204.
FIPS 204 specifies ML-DSA for generating and verifying digital signatures and states that ML-DSA is believed secure even against adversaries with a large-scale quantum computer.
