Class CombinedOperations

java.lang.Object

co.ankatech.ankasecure.sdk.operations.CombinedOperations

public final class CombinedOperations
extends Object

Combined cryptographic operations facade.

Public facade for combined operations (re-encryption, re-signature, sign-then-encrypt, decrypt-then-verify, and utility operations with external keys). All methods are exposed via AuthenticatedSdk.

Stateful signing keys

The operations that produce a signature — resign* (with the new key) and signThenEncrypt* (with the signing key) — can be refused for a stateful hash-based key (XMSS, XMSS^MT, LMS/HSS) with SdkErrorCode.STATEFUL_KEY_EXHAUSTED (rotate the key; do not retry) or SdkErrorCode.STATEFUL_KEY_BUSY (retry after AnkaSecureSdkException.getRetryAfterSeconds()), decided before any output exists. A streaming re-sign reserves the one-time signature before it reads the request body, so a request then refused for its body still spends one.

                    throws AnkaSecureSdkException

Throws:

AnkaSecureSdkException

resign

public ResignResult resign(String newKid,
 String sourceKid,
 String jws,
 JwsSerialization serialization)
                    throws AnkaSecureSdkException

Re-signs a JWS with an explicit JWS serialization selection. Ergonomic overload of resign(String, String, String); a null serialization defers to the server.

Parameters:

newKid - destination key identifier; must not be null

sourceKid - the signer whose signature is replaced, or null when the protected header names one key

jws - the JWS to re-sign (compact or JWS-JSON); must not be null

serialization - requested serialization, or null to let the server choose

Returns:

re-signature result; never null

Throws:

AnkaSecureSdkException - on error, including HTTP 400 when COMPACT is requested but the deployment mandates a qualified timestamp

NullPointerException - if newKid or jws is null

resignFileCompact

public ResignResult resignFileCompact(String newKid,
 String sourceKid,
 Path input,
 Path output)
                               throws AnkaSecureSdkException

Throws:

AnkaSecureSdkException

resignFileCompact

public ResignResult resignFileCompact(String newKid,
 String sourceKid,
 Path input,
 Path output,
 JwsSerialization serialization)
                               throws AnkaSecureSdkException

Re-signs a file with an explicit JWS serialization selection. Ergonomic overload of resignFileCompact(String, String, Path, Path); a null serialization defers to the server. When the server mandates a qualified timestamp, the written output is a JWS-JSON artifact carrying the JAdES sigTst.

Parameters:

newKid - destination key identifier; must not be null

sourceKid - the signer whose signature is replaced, or null when the protected header names one key

input - input JWS file (compact or JWS-JSON); must not be null

output - output file; must not be null

serialization - requested serialization, or null to let the server choose

Returns:

re-signature result; never null

Throws:

AnkaSecureSdkException - on error, including HTTP 400 when COMPACT is requested but the deployment mandates a qualified timestamp

NullPointerException - if newKid, input, or output is null

resignFileStream

public ResignResult resignFileStream(Path oldJwsHeader,
 String newKid,
 String sourceKid,

                              throws AnkaSecureSdkException

Throws:

AnkaSecureSdkException

 String encryptKid,
 byte[] data)
                                  throws AnkaSecureSdkException

Throws:

signThenEncrypt

public SignEncryptResult signThenEncrypt(String signKid,
 String encryptKid,
 byte[] data,
 JwsSerialization serialization)
                                  throws AnkaSecureSdkException

Signs then encrypts with an explicit inner-JWS serialization selection. Ergonomic overload of signThenEncrypt(String, String, byte[]); a null serialization defers to the server. Governs only the inner JWS representation and never changes the outer JWE.

Parameters:

signKid - private key identifier for signing; must not be null

encryptKid - public key identifier for encryption; must not be null

data - plaintext bytes to sign and encrypt; must not be null

serialization - requested inner-JWS serialization, or null to defer

Returns:

combined sign-encrypt result; never null

Throws:

AnkaSecureSdkException - on error, including HTTP 400 (before any signing or encryption) when COMPACT is requested but the deployment mandates a qualified timestamp

NullPointerException - if any of signKid, encryptKid, or data is null
