Upgraded native crypto library to v2.2.5 which fixes a critical memory leak issue.

Fixed

• Web Worker version ofsignThenEncryptAsync adding an empty byte array as the signerId instead of ignoring it when it is not provided.

• Increased timeouts in long-running browser tests.

Fixed

• C++ addon download script creating an empty file in case of network error

Added

• Ability to use encrypted private key to signThenEncrypt and decryptThenVerify methods.
• Ability to store an identifier of the signing key in cipherdata to signThenEncrypt method.
• Ability to verify the attached signature with one of several public keys to decryptThenVerify method.

Fixed

• Memory leaks in browsers

Fixed:

• Export correct version of Buffer in browsers

Breaking changes

• All api functions now take byte arrays as Buffers (Browsers, Node.js)
• generateKeyPair takes options object as parameter
• KeysTypesEnum renamed to KeyPairType
• generateValidationToken method removed

Added

• signThenEncrypt
• decryptThenVerify
• privateKeyToDER
• publicKeyToDER
• changePrivateKeyPassword
• encryptPrivateKey
• decryptPrivateKey

Added new functions:
Node.js/Borwser

• signThenEncrypt
• decryptThenVerify

Browser only

• signThenEncryptAsync
• decryptThenVerifyAsync
