# MLDSA65.PublicKey The public key for MLDSA65. ``` struct PublicKey ``` ## Topics ### Creating a public key [`init(rawRepresentation: D) throws`](/documentation/CryptoKit/MLDSA65/PublicKey/init(rawRepresentation:)) Parses a public key from a serialized representation. ### Getting the raw representation [`var rawRepresentation: Data`](/documentation/CryptoKit/MLDSA65/PublicKey/rawRepresentation) A serialized representation of the public key. ### Validating a signature ### Instance Methods [`func isValidSignature(S, for: D) -> Bool`](/documentation/CryptoKit/MLDSA65/PublicKey/isValidSignature(_:for:)) Verifies a MLDSA65 signature. [`func isValidSignature(S, for: D, context: C) -> Bool`](/documentation/CryptoKit/MLDSA65/PublicKey/isValidSignature(_:for:context:)) Verifies a MLDSA65 signature, in a specific context. ## Relationships ### Conforms To [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`Sendable`](/documentation/Swift/Sendable) --- Copyright © 2026 Apple Inc.
