RSA(Rivest-Shamir-Adleman) is an Asymmetric encryption technique that uses two different keys as public and private keys to perform the encryption and decryption. With RSA, you can encrypt sensitive information with a public key and a matching private key is used to decrypt the encrypted message. Asymmetric encryption is mostly used when there are 2 different endpoints are involved such as VPN client and server, SSH, etc.

Below is an online tool to perform RSA encryption and decryption as a RSA calculator.

For Java implementation of RSA, you can follow this article.

First, you need to transform the private key to the form of RSA parameters. Then you need to pass the RSA parameters to the RSA algorithm as the private key. Lastly, you use the JWT library to. Usage Guide - RSA Encryption and Decryption Online. In the first section of this tool, you can generate public or private keys. To do so, select the RSA key size among 515, 1024, 2048 and 4096 bit. C# (pronounced see sharp, like the musical note C♯, but written with the number sign) b is a general-purpose, multi-paradigm programming language encompassing strong typing, lexically scoped, imperative, declarative, functional, generic, object-oriented (class -based), and component-oriented programming disciplines. C# - generate - rsa private key xml format. How to store/retrieve RSA public/private key (4) I want to use RSA public key encryption. What is the best way to store or retrieve private and public keys? Is XML a good idea here? 65537 (it is convention that all RSA public keys use 65537 as their exponent).

Storefront 2.6 generate new security keys. Some of the Citrix documentation content is machine translated for your convenience only. The official version of this content is in English. Web Interface sites enable user devices to connect to the server farm.

First, we require public and private keys for RSA encryption and decryption. Hence, below is the tool to generate RSA key online. It generates RSA public key as well as the private key of size 512 bit, 1024 bit, 2048 bit, 3072 bit and 4096 bit with Base64 encoded.

By default, the private key is generated in PKCS#8 format and the public key is generated in X.509 format.

RSA Encryption and Decryption Online

Below is the tool for encryption and decryption. Either you can use the public/private keys generated above or supply your own public/private keys.

Serial key. Any private or public key value that you enter or we generate is not stored on this site, this tool is provided via an HTTPS URL to ensure that private keys cannot be stolen.

This tool provides flexibility for RSA encrypt with public key as well as private key along with RSA decrypt with public or private key.

Usage Guide - RSA Encryption and Decryption Online

In the first section of this tool, you can generate public or private keys. To do so, select the RSA key size among 515, 1024, 2048 and 4096 bit click on the button. This will generate the keys for you.

For encryption and decryption, enter the plain text and supply the key. As the encryption can be done using both the keys, you need to tell the tool about the key type that you have supplied with the help of radio button. By default, public key is selected. Then, you can use the cipher type to be used for the encryption. The different cipger options are RSA, RSA/ECB/PKCS1Padding and RSA/ECB/OAEPWithSHA-1AndMGF1Padding. Now, once you click the encrypt button the encrypted result will be shown in the textarea just below the button.

Remember, the encrypted result is by default base64 encoded.

Similarly, for decryption the process is same. Here, you need to enter the RSA encrypted text and the result will be a plain-text. You have both options to decrypt the encryption with public and private keys.

C-- (pronouncedcee minus minus) is a C-like programming language. Its creators, functional programming researchers Simon Peyton Jones and Norman Ramsey, designed it to be generated mainly by compilers for very high-level languages rather than written by human programmers. Unlike many other intermediate languages, its representation is plain ASCII text, not bytecode or another binary format.^[1][2]

There are two main branches of C--. One is the original C-- branch, with the final version 2.0 released in May 2005.^[3] The other is the Cmm fork actively used by the Glasgow Haskell Compiler as its intermediate representation.^[4]

Design[edit]

C-- is a 'portable assembly language', designed to ease the task of implementing a compiler which produces high quality machine code. This is done by having the compiler generate C-- code, delegating the harder work of low-level code generation and optimisation to a C-- compiler.

Work on C-- began in the late 1990s. Since writing a custom code generator is a challenge in itself, and the compiler back ends available to researchers at that time were complex and poorly documented, several projects had written compilers which generated C code (for instance, the original Modula-3 compiler). However, C is a poor choice for functional languages: it does not guarantee tail call optimization, or support accurate garbage collection or efficient exception handling. C-- is a simpler, tightly-defined alternative to C which does support all of these things. Its most innovative feature is a run-time interface which allows writing of portable garbage collectors, exception handling systems and other run-time features which work with any C-- compiler.

The language's syntax borrows heavily from C. It omits or changes standard C features such as variadic functions, pointersyntax, and aspects of C's type system, because they hamper certain essential features of C-- and the ease with which code-generation tools can produce it.

The name of the language is an in-joke, indicating that C-- is a reduced form of C, in the same way that C++ is basically an expanded form of C. (In C-like languages, '--' and '++' are operators meaning 'decrement' and 'increment'.)

The first version of C-- was released in April 1998 as a MSRA paper,^[1] accompanied by a January 1999 paper on garbage collection.^[2] A revised manual was posted in HTML form in May 1999.^[5] Two sets of major changes proposed in 2000 by Norman Ramsey ('Proposed Changes') and Christian Lindig ('A New Grammar') lead to C-- version 2, which was finalized around 2004 and officially released in 2005.^[3]

Type system[edit]

The C-- type system is deliberately designed to reflect constraints imposed by hardware rather than conventions imposed by higher-level languages. In C--, a value stored in a register or memory may have only one type: bit vector. However, bit vector is a polymorphic type and may come in several widths, e.g., bits8, bits32, or bits64. A separate 32-or-64 bit family of floating-point types is supported. In addition to the bit-vector type, C-- also provides a Boolean type bool, which can be computed by expressions and used for control flow but cannot be stored in a register or in memory. As in an assembly language, any higher type discipline, such as distinctions between signed, unsigned, float, and pointer, is imposed by the C-- operators or other syntactic constructs in the language.

C-- version 2 removes the distinction between bit-vector and floating-point types. Programmers are allowed to annotate these types with a string 'kind' tag to distinguish, among other things, a variable's integer vs float typing and its storage behavior (global or local). The first part is useful on targets that have separate registers for integer and floating-point values. In addition, special types for pointers and the native word is introduced, although all they do is mapping to a bit vector with a target-dependent length.^[3]:10 C-- is not type-checked, nor does it enforce or check the calling convention.^:28

Implementations[edit]

The specification page of C-- lists a few implementations of C--. The 'most actively developed' compiler, Quick C--, was abandoned in 2013.^[6]

Haskell[edit]

A C-- dialect called Cmm is the intermediate representation for the Glasgow Haskell Compiler.^[7] GHC backends are responsible for further transforming C-- into executable code, via LLVM IR, slow C, or directly through the built-in native backend.^[8]

Some of the developers of C--, including Simon Peyton Jones, João Dias, and Norman Ramsey, work or have worked on the Glasgow Haskell Compiler. Work on GHC has also led to extensions in the C-- language, forming the Cmm dialect. Cmm uses the C preprocessor for ergonomics.^[4]

Despite the original intention, GHC does perform many of its generic optimizations on C--. As with other compiler IRs, GHC allows for dumping the C-- representation for debugging.^[9] Target-specific optimizations are, of course, performed later by the backend.
