implementing-digital-signatures-with-ed25519

separate

Implements digital signatures using the Ed25519 algorithm (Curve25519), covering key-pair generation, signing, signature verification, and security tradeoffs versus RSA and ECDSA. Use when adding message or artifact signing and authentication-integrity checks to a system, or when advising on Ed25519 key properties and validation criteria.

When to use

• When deploying or configuring implementing digital signatures with ed25519 capabilities in your environment
• When establishing security controls aligned to compliance requirements
• When building or improving security architecture for this domain
• When conducting security assessments that require this implementation

When not to use

• key recovery from signatures
• NIST federal use cases requiring Ed448
