Visual Basic. Pre-Alpha 17 Mature 7 Inactive 5. Freshness Recently updated It should allow you to sign, encrypt , decrypt , and verify any kind of text, in particular e-mails, as well as managing keys. Version 3. We use native implementations on browsers and Node. Easy and fast file sharing from the command-line. This code contains the server with everything you need to create your own instance. For easy deployment, we've created a Docker container.

For the usage with a AWS S3 Bucket, you just need to specify the following options, provider, aws-access-key, aws-secret-key, bucket, and s3-region. If you specify the ShardingSphere Distributed database ecosphere. They all provide functions of data scale out, distributed transaction and distributed governance, applicable in a variety of situations such as Java isomorphism, heterogeneous language and cloud native.

Apache ShardingSphere aiming at reasonably making full use of the computation and storage capacity of existed database Tink A library that provides cryptographic APIs that are easy and secure. At Google, Tink has been deployed in hundreds of products and systems.

Cryptography is difficult to get right. With Tink, you can encrypt or sign data with just a few lines of code, with built-in security guarantees to help you avoid pitfalls. Tink adds security protections on top of well known libraries like BoringSSL and Java Cryptography Architecture and shows them right in the interfaces, so auditors and tools can quickly find gaps.

Jackcess Encrypt. OpenKM is a Web 2. Due to its The Stanford Javascript Crypto Library is a project by the Stanford Computer Security Lab to build a secure, powerful, fast, small, easy-to-use, cross-browser library for cryptography in Javascript.

SJCL is small but powerful. The minified version of the library is under 6. SJCL is secure. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

The public key can be distributed, but the private key needs to be secured properly. The public keys is saved into a file with the extension.

Both keys are stored in binary format. For restoring the keys, we need to use specific classes for each. The public key is saved in X. We now have two keys with us: a public key and a private key.

Which of these should we use for encryption? Remember that if you encrypt your data with the private key, then the encrypted data can only be decrypted with the public key. Since the public key is, by definition public , anyone can get at this key. So using this method of encrypting with the private key serves the purpose of non-repudiation i. Another way of putting it is that the recipient can be sure that the data came from you.

This is the basis of secure data interchange between a client program and a server program. The client needs to be sure that the data came from the server, without any middlemen tampering with the data. This method then serves as a method of secure file exchange with Alice.

In the following examples, we demonstrate using the private key for encryption. To go the other way, you can replace the private key with the public key.
