       crypto/subtle/rsassa-pkcs1-v1_5-import-jwk.html

* WebCore.xcodeproj/project.pbxproj: Added new files.

* bindings/js/JSCryptoAlgorithmBuilder.cpp:
(WebCore::JSCryptoAlgorithmBuilder::add):
* bindings/js/JSCryptoAlgorithmBuilder.h:
* crypto/CryptoAlgorithmDescriptionBuilder.h:
Added a way to add an Uint8Array, as needed for RSA key.algorithm.publicExponent.

* bindings/js/JSCryptoAlgorithmDictionary.cpp:
(WebCore::createAesCbcParams): Removed unneeded JSC prefixes.
(WebCore::createAesKeyGenParams): Ditto.
(WebCore::createHmacParams): Ditto.
(WebCore::createHmacKeyParams): Ditto.
(WebCore::createRsaKeyGenParams): Added.
(WebCore::createRsaSsaKeyParams): Added. WebCrypto currently doesn't specify any
parameters for importKey, so the structure remains blank (unlike with JWK).
(WebCore::createRsaSsaParams): Added (currently unused, will be sued for sign/verify soon).
(WebCore::JSCryptoAlgorithmDictionary::createParametersForEncrypt): Removed unneeded JSC prefixes.
(WebCore::JSCryptoAlgorithmDictionary::createParametersForDecrypt): Ditto.
(WebCore::JSCryptoAlgorithmDictionary::createParametersForSign): Added support for RSAES_PKCS1_v1_5.
(WebCore::JSCryptoAlgorithmDictionary::createParametersForVerify): Ditto.

* bindings/js/JSCryptoKeySerializationJWK.cpp:
(WebCore::getJSArrayFromJSON): Added.
(WebCore::getBigIntegerVectorFromJSON): Added.
(WebCore::createRSASSAKeyParameters): Create parameters for key import. The key
will remember which algorithm it's allowed to be used with.
(WebCore::JSCryptoKeySerializationJWK::reconcileAlgorithm): Added support for
RS256...RS512 (tha is, RSAES_PKCS1_v1_5 with SHA-256...SHA-512).
(WebCore::JSCryptoKeySerializationJWK::keyDataOctetSequence): Split out of keyData().
(WebCore::JSCryptoKeySerializationJWK::keyDataRSAComponents): Added code to read
RSA key components from JWK.
(WebCore::JSCryptoKeySerializationJWK::keyData): Call one of the above functions.

Placeholders.

(WebCore::CryptoAlgorithmHMAC::sign):
(WebCore::CryptoAlgorithmHMAC::verify):
Switched from "as" functions to "is" and "to" ones, as that's more idiomatic.

* crypto/algorithms/CryptoAlgorithmRSASSA_PKCS1_v1_5.cpp: Added.

sure that hasLength is never left uninitialized, even when reading formats that
don't contain a length.

* crypto/parameters/CryptoAlgorithmRsaKeyGenParams.h: Added.
* crypto/parameters/CryptoAlgorithmRsaSsaKeyParams.h: Added.
* crypto/parameters/CryptoAlgorithmRsaSsaParams.h: Added.
Added parameter structures that are needed for RSASSA_PKCS1_v1_5.

LayoutTests:

* crypto/subtle/resources/common.js:
(hexToArrayBuffer): Fixed a typo
(Base64URL.stringify):
(Base64URL.parse):
Added helpers to deal with Base64URL, as needed for JWK.
