The 19 pages that link to Digital signature, each with the reason it gives.

• CryptographyRelated: Signatures provide authentication and integrity without keeping the signed message secret.

• Public-key cryptographyBroader topic: It reverses the intuitive encryption direction: the private key signs, and the public key verifies.

• CryptocurrencyRelated: Nodes use signatures to check that a transaction was authorized by the relevant key holder.

• Cryptographic hash functionRelated: Signature schemes commonly sign a digest rather than an entire long message.

• End-to-end encryptionRelated: Encryption does not by itself prove who sent a message.

• EncryptionCompared with: Signatures establish authenticity and integrity, while encryption primarily provides confidentiality.

• Transport Layer SecurityRelated: Signatures let a client verify that handshake messages came from the certificate holder.

• BitcoinRelated: Signatures prove that transaction inputs were authorized without revealing private keys.

• Birthday ProblemRelated: Birthday-style collision attacks can undermine signatures built on insufficiently long hashes.

• Identity documentRelated: Electronic credentials use signatures to let verifiers detect forged or modified data.

• BlockchainRelated: Signatures let nodes verify who authorized a transaction without revealing private keys.

• Document management systemRelated: Signatures can provide evidence that an approved document has not been altered.

• Public key infrastructureRelated: Certificate issuers sign certificates so verifiers can detect changes and authenticate the issuer.

• ExecutableRelated: Signatures can help verify an executable's publisher and detect modification.

• OpenDocumentRelated: OpenDocument packages can carry signatures that authenticate document contents.

• Byzantine fault toleranceRelated: Signatures constrain how traitors can lie, sharply reducing the message complexity of agreement.

• Crypto-anarchyRelated: Signatures can establish authenticity without revealing a signer's legal identity.

• Document file formatRelated: Changes made during format conversion can invalidate signatures attached to documents.

• DownloadRelated: Signatures help verify the publisher and integrity of downloaded software.
