Triple DES Encryption and Decryption Online Tool. Triple DES or DESede , a symmetric-key algorithm for the encryption of electronic data, is the successor of DES (Data Encryption Standard) and provides more secure encryption then DES. The Triple DES breaks the user-provided key into three subkeys as k1, k2, and k3.

Calculate the exclusive or (XOR) with a simple web-based calculator. Input and output in binary, decimal, hexadecimal or ASCII. XOR Calculator. Provide two inputs, select input and output types, then Calculate XOR I. Input: II. Input: Calculate XOR III. Output: The form calculates the bitwise exclusive or using the function gmp_xor. At the bit level, there are four possibilities,. The one-time pad is theoretically 100% secure. It is also an easy cipher to perform manually. It was first described by Frank Miller in 1882, and then reinvented in 1917. It is built on modular addition, similar to the Vigenère cipher, but without repeating the key. In 1919, a variant of the one-time pad, the Vernam cipher, was patented by.

This is a programmable multiple-precision hex calculator with many utilities. With Hpmbcalc, you can easily perform a lot of big number math and encryption operations, such as: square root, modular inverse; hash, CRC, and check sum make; shift..

Sodium is a modern, easy-to-use software library for encryption, decryption, signatures, password hashing, and more. It is a portable, cross-compilable, installable, and packageable fork of NaCl, with a compatible but extended API to improve usability even further. Its goal is to provide all of the core operations needed to build higher-level cryptographic tools. Sodium is cross-platform.

Homomorphic encryption is a form of encryption that allows to perform calculations on encrypted data without decrypting it first. The result of such computation is produced in encrypted form. When decrypted, the output is the same as if the calculations had been performed on the unencrypted data. [ Wikipedia ].

在线AES加密解密工具。 AES采用对称分组密码体制，密钥长度支持为128/192/256bits。 用户密钥长度不足时，平台将以0x00自动填充。 IV也一样，自动填充，超出部分将被忽略。 加密时会将明文数据按16byte进行分组，不足16byte时将用特定的Padding（如PCKS7）字符进填充，所以不同的Padding方式密文最后一段可能不一样。 如果没有特别指明平台将使用UTF8编码处理数据（如KEY/IV）。 本工具未作全面测试，如果发现问题请给予反馈。 DES TripleDes AES RSA SM2 SM4 SM3.

Encryption is done with c (m) = m^e mod n where c is the ciphertext and m is the message. Note that both of these values must be integers 1 < m < n and 1 < c < n . Decryption is done with m (c) = c^d mod n . m: c: Attacks Factoring the public modulus n The public modulus n is equal to a prime number p times a prime number q.

RSA encryption usually is only used for messages that fit into one block. A 1024-bit RSA key invocation can encrypt a message up to 117 bytes, and results in a 128-byte value. A 2048-bit RSA key invocation can encrypt a message up to 245 bytes. RSA, as defined by PKCS#1, encrypts "messages" of limited size,the maximum size of data which can be.
