Class WebCryptoExtendedProvider

Extended WebCryptoProvider that adds support for additional algorithms such as MD5 hashing, AES ECB mode, and certain PBE algorithms.

Note: This implementation uses the 'node-forge' library for RSA encryption/decryption with PKCS#1 v1.5 padding, as WebCrypto does not support this mode directly.

Caution: MD5 is considered cryptographically weak and should be used with caution. This provider is intended for compatibility with legacy systems and not for secure applications.

Example

const provider = new WebCryptoExtendedProvider();
const hash = await provider.digest(data, 'MD5');
const encrypted = await provider.encryptSymmetric(data, key, { type: 'AES_128_ECB' });
const decrypted = await provider.decryptSymmetric(encryptedData, key, { type: 'AES_128_ECB' });
const rsaEncrypted = await provider.encrypt(data, publicKeyInfo, { type: 'RSASSA_PKCS1_v1_5' });
const rsaDecrypted = await provider.decrypt(rsaEncryptedData, privateKeyInfo, { type: 'RSASSA_PKCS1_v1_5' });
