A cryptographic algorithm used to generate and verify digital signatures, commonly based on RSA or ECC (Elliptic Curve Cryptography).

In public key cryptography, this is the key that is distributed to the public to encrypt messages for a particular receiver or to verify a digital signature.

The output of a hash function that uniquely represents the content of a message, providing a digital fingerprint used in digital signatures.

The process of converting information or data into a code, especially to prevent unauthorized access.

The process of verifying the identity of a person or device, often through the use of digital signatures.

A set of roles, policies, hardware, software, and procedures needed to create, manage, distribute, use, store, and revoke digital certificates and manage public-key encryption.

A physical device used to gain access to an electronically restricted resource, often storing cryptographic keys to facilitate digital signature operations.

Software that performs cryptographic operations such as hashing, digital signatures, and encryption. CSPs are often part of an operating system's security infrastructure.

A type of public-key cryptography based on the algebraic structure of elliptic curves over finite fields which provides the same level of security with smaller keys compared to non-EC cryptography.

In public key cryptography, this is the secret key that is used by the receiver to decrypt messages or by the sender to create a digital signature.

An entity that issues digital certificates, especially SSL certificates, and vouches for the binding between the individual or organization identity and the public key.

The process of converting encrypted information or data back into its original form, so it can be understood.

Protocols for secure communication over a computer network which provide security through the use of certificates and digital signatures.

A list of revoked digital certificates that is published and regularly updated by the certificate authority (CA), indicating that the listed certificates should not be trusted.

A portable card embedded with integrated circuits that are capable of providing strong security authentication for single sign-on (SSO) within large organizations and are also used to carry and use digital signatures.

A digital code (generated and authenticated by public key encryption) that is attached to an electronically transmitted document to verify its contents and the sender's identity.

A property of a digital signature ensuring that a party cannot deny the authenticity of their signature on a document.

The process of applying a digital signature to a document, which involves the creation of a message digest and its encryption using the signer’s private key.

An electronic document that uses a digital signature to bind a public key with an entity's identity and can be used to verify that a public key belongs to an individual, system, or entity.

In cryptography, this refers to the two keys used in asymmetric encryption methods: a public key which anyone can use to encrypt a message, and a private key for decryption used only by the receiver.

An event that occurs when two different inputs to a hash function produce identical outputs, compromising the uniqueness of digital signatures.

A cryptographic system that uses pairs of keys: public keys which may be disseminated widely, and private keys which are known only to the owner.

A function that converts an input (or 'message') into a fixed-size string of bytes, typically for security or data integrity purposes.

A Federal Information Processing Standard for digital signatures which employs a pairing of large prime numbers for its operation.

The process of securely keeping track of the creation and modification time of a document, which can provide proof of the existence of the document at a specific moment in time.

An algorithm used by modern computers to encrypt and decrypt messages, and one of the first systems to provide digital signatures and public-key cryptography.

The framework within which multiple parties can share resources or information securely and reliably, such as the public key infrastructure (PKI) trust model for digital certificates.

A standard defining the format of public key certificates which are used in many Internet protocols as well as offline applications.

A family of cryptographic hash functions designed by the National Security Agency (NSA) and commonly used in digital signatures.
