Add System.Crypto methods to TIA

[benjaminloerincz]

Add these methods of namespace System, class Crypto to TIA:

• System.Crypto.decrypt(String algorithmName, Blob privateKey, Blob initializationVector, Blob cipherText)
• System.Crypto.decryptWithManagedIV(String algorithmName, Blob privateKey, Blob IVAndCipherText)
• System.Crypto.encrypt(String algorithmName, Blob privateKey, Blob initializationVector, Blob clearText)
• System.Crypto.encryptWithManagedIV(String algorithmName, Blob privateKey, Blob clearText)
• System.Crypto.generateAesKey(Integer size)
• System.Crypto.generateDigest(String algorithmName, Blob input)
• System.Crypto.generateMac(String algorithmName, Blob input, Blob privateKey)
• System.Crypto.getRandomInteger()
• System.Crypto.getRandomLong()
• System.Crypto.sign(String algorithmName, Blob input, Blob privateKey)
• System.Crypto.signWithCertificate(String algorithmName, Blob input, String certDevName)
• System.Crypto.verify(String algorithmName, Blob data, Blob signature, Blob publicKey)
• System.Crypto.verify(String algorithmName, Blob data, Blob signature, String certDevName)
