parsePrivateKey

Parses a private key from PEM (EC) or base64 (Ed25519) format. Parameters: keyData (String) - the key data (PEM string or base64 encoded) Returns: PrivateKey - the parsed private key Throws: [KeyParseException](/sdks/cdp-sdks-v2/java/com/coinbase/cdp/auth/exceptions/KeyParseException "class in com.coinbase.cdp.auth.exceptions") - if parsing fails

​
parseWalletKey

Parses a wallet secret (base64 DER-encoded EC key). Parameters: walletSecret (String) - the base64-encoded PKCS#8 DER key Returns: PrivateKey - the parsed private key Throws: [KeyParseException](/sdks/cdp-sdks-v2/java/com/coinbase/cdp/auth/exceptions/KeyParseException "class in com.coinbase.cdp.auth.exceptions") - if parsing fails

​
isEd25519Key

Determines if a key is an Ed25519 key (EdDSA). Parameters: key (PrivateKey) - the private key Returns: boolean - true if the key uses Ed25519/EdDSA algorithm
