Opal
Opal is a ruby to JavaScript Source-to-source compiler. It also have an implementation of the Ruby Corelib.
Opal is hosted on GitHub, and there are a freenode IRC channel at #opal, ask questions Onstackoverflow (tag #opalrb).
With the development of VoIP and NGN technology, the Openh323 era is about to transition to the SIP era, in the open-source protocol stack, which occupies a dominant position, it puts a complex and advanced protocol stack presented in the eyes of ordinary programmers, which has made a contribution to the popularization of the system. However, when in the SIP era, there has been a state of separatist, SIP is relatively simple, flexible, and various protocol stacks, the following will be detailed

Just one day before the Chinese New Year's Eve, it's close to you to go home. Some people are excited, because they will have to go through the annual installation drama in a few days, and all the parties, including relatives, friends, and students, will show off, therefore, I have to pay a year-end
Symmetric encryption and asymmetric encryption, asymmetric encryption
What is encryption? Encryption is divided into two parts: algorithm and key. The algorithm remains unchanged, and the key changes. For more information, see the following example.
Key: abcedfgh-> 12345678.
When it comes to encryption, it's reminiscent of digital signatures, what are the two often confusing concepts?Encryption: Encryption is a way to send information in a password. Only the person with the correct key can unlock the password for this message. For others, the message looks like a series of random letters, numbers, and symbols.
When it comes to encryption, a digital signature is associated with two concepts that are often confused.
Encryption: Encryption is a way to send information in a password way. Only the person with the correct key can unlock the password for this information. For other people, this information looks like a series of random letters, numbers, and symbols.
[Preface]This article briefly introduces the concepts related to encryption technology, and finally summarizes the existing encryption technology in java as well as its usage and examples.
[Simple encryption]
1. Simple concept
Plaintext: the information before encryption
Ciphertext: Confidential Information
Algorithm
For security reasons, we typically choose an encryption method to encrypt text that requires security, while BASE64 encryption and DES64 encryption are common cryptographic algorithms. I remember what I used in the previous project was the combination of these two cryptographic algorithms: Base64 + des encryption. Of c
Java encryption algorithm--MD5 encryption and hash hashing with secret key encryption algorithm source code
Recently learned encryption algorithm knowledge, using MD5 encryption, Baidu a lot of online data, not very detailed, here on how to implement the MD5
Symmetric encryption and asymmetric encryption, asymmetric encryptionSafe communication methods must meet the following three conditions:1. Integrity, that is, the message has not been tampered with midway through.2. Confidentiality, which cannot be decrypted by a third party.3. verifiable. The message receiver can determine who sent the message.
Symmetric encryption
The example of this paper describes the Base64 encryption, MD5 encryption and SHA1 encryption implemented by JS. Share to everyone for your reference, specific as follows:

The RSA algorithm is the first algorithm that can be used for both data encryption and digital signature. It is easy to understand and operate, and is also popular. Its security is based on the difficulty of big integer factorization, while the big integer factorization is a famous mathematical problem. So far, there is no effective solution, therefore, the security of the RSA algorithm can be ensured.
The RSA algorithm consists of the generation of
Comments: Piracy is a worrying issue for most software developers. Will the software encrypted with encryption locks be cracked by hackers? Theoretically, there is no software that cannot be cracked. Even pure mathematical encryption may be cracked, but the time for cracking may be an astronomical number. Currently, there are two types of encryption locks on the
