    Algorithms

    Select to enable algorithms available to users in your account when creating a keypair:

    • RSA

      Rivest–Shamir–Adleman (RSA) is a widely-used and compatible with various systems and protocols. RSA is a trusted choice for applications requiring broad compatibility and established security practices.

    • ECDSA

      Elliptic Curve Digital Signature Algorithm (ECDSA) is suitable for resource-constrained environments like mobile devices and IoT devices. ECDSA provides strong security with shorter key lengths compared to traditional RSA.

    • EdDSA

      Edwards-curve Digital Signature Algorithm (EdDSA) offers strong resistance against various cryptographic attacks while maintaining efficiency. EdDSA is recommended for applications where security is paramount, such as digital signatures and secure communications.

    • MLDSA (Quantum-safe)

      Module-Lattice-Based Digital Signatures Algorithm (MLDSA) is a quantum-safe approach to cryptographic security. It relies on the difficulty of solving lattice-based problems, which makes it resistant to attacks from quantum computers.

    • SLHDSA (Quantum-safe)

      Secure Lightweight Hash-based Digital Signature Algorithm (SLHDSA) is a quantum-safe approach to cryptographic security. It is designed to offer robust protection with minimal computational overhead. It leverages lightweight hash-based techniques to ensure security while optimizing performance, making it ideal for resource-constrained environments.

    Size/Curve

    Enable or disable the key sizes or curves available to users in your account when creating a keypair.

    The following key sizes are available for RSA algorithms:

    • 2048

      A 2048-bit key size is one of the most commonly used key sizes in asymmetric cryptography, particularly in RSA encryption.

    • 3072

      A 3072-bit key size provides higher cryptographic strength compared to 2048-bit keys.

    • 4096

      A 4096-bit key size offers the highest level of cryptographic security among the RSA options.

    Key curve Ed25519 is available for EdDSA.

    The following key curves are available for ECDSA algorithms:

    • P-192

      NIST P-192, also known as secp192r1 refers to an elliptic curve defined over a 192-bit prime field.

    • P-256

      NIST P-256, also known as secp256r1 is an elliptic curve defined over a 256-bit prime field. This curve has a higher security level that P-192 due to its longer key length.

    • P-384

      NIST P-384, also known as secp384r1 is an elliptic curve defined over a 384-bit prime field. This curve offers a significantly higher level of security compared to P-256, as it utilizes a longer key length and larger computational parameters.

    The following security levels are available for MLDSA algorithms:

    • MLDSA-44

      Represents a cryptographic strength equivalent of at least 128-bit symmetric encryption. This level of security is considered sufficient for many applications requiring strong security, such as protecting sensitive data and communications.

    • MLDSA-65

      Represents a higher cryptographic strength equivalent to at least 192-bit symmetric encryption. Offers increased security margin compared to Security Level 44, making it suitable for applications demanding elevated security requirements.

    • MLDSA-87

      Represents an even higher level of cryptographic strength of at least 256-bit symmetric encryption, surpassing the previous two levels. Equivalent to an even greater bit length in symmetric encryption, further increasing the complexity for potential attackers. Offers the highest level of security among the mentioned levels, suitable for extremely sensitive applications requiring maximum protection against advanced cryptographic attacks.

    The following security levels are available for SLHDSA algorithms:

    • SHA2-128s
