OpenSSL is a powerful cryptography toolkit that can be used for encryption of files and messages. If you want to use the same password for both encryption of plaintext and decryption of ciphertext, then you have to use a method that is known as symmetric-key algorithm.

Normally, a block encryption algorithm (AES, Blowfish, DES, RC2, etc.) emit encrypted output that is a multiple of the block size (16 bytes for AES as an example). With CTR mode, the number of bytes output is exactly equal to the number of bytes input, so no padding/unpadding is required. The PaddingScheme property does not apply for counter mode.

AES Crypt is an advanced file encryption utility that integrates with the Windows shell or runs from the Linux command prompt to provide a simple, yet powerful, tool for encrypting files using the Advanced Encryption Standard (AES). AES (Advanced Encryption Standard), also known as Rijndael encryption method in cryptography, is a block encryption standard adopted by the federal government of the United States. This standard is used to replace the original DES, which has been widely used all over the world and has become one of the most popular symmetric key algorithms.

This standard is used to replace the original DES, which has been widely used all over the world and has become one of the most popular symmetric key algorithms. The AES cipher is used in CBC (cipher block chaining) mode. Data is encrypted and decrypted in 512 byte chains. aespipe supports three key setup modes; single-key, multi-key-v2 and multi-key-v3 modes. Single-key mode uses simple sector IV and one AES key to encrypt and decrypt all data sectors. Multi-key-v2 mode uses cryptographically more secure MD5 IV and 64 different AES keys to encrypt and decrypt data sectors. This is an implementation in Tcl of the Advanced Encryption Standard (AES) as published by the U.S. National Institute of Standards and Technology [1]. AES is a 128-bit block cipher with a variable key size of 128, 192 or 256 bits.

SERPENT: Serpent is a 128-bit block cipher designed by Ross Anderson, Eli Biham and Lars Knudsen as a candidate for the Advanced Encryption Standard. Serpent's design was limited to well understood mechanisms, so that could rely on the wide experience of block cipher cryptanalysis, and achieve the highest practical level of assurance that no ...

When using the password form of the command, the salt is output at the start of the data stream. When using -a you are encoding the salt into the base64 data.. The Key + IV method does not need salt, and openssl does not remove it from the decoded base64 string. RSA isn't designed to encrypt any arbitrary string, it's an algorithm that encrypts an integer. Specifically, an integer from 0 to n-1 where n is the modulus value from the public key. When you talk about a RSA key that's 1024 bits, that means it takes 1024 bits to store the modulus in binary.

Specifically, each IV is encrypted with AES-256 where the AES-256 key is the SHA-256 hash of the file’s data encryption key. With DIRECT_KEY policies, the file’s nonce is appended to the IV. Currently this is only allowed with the Adiantum encryption mode. Symmetric Ciphers Online allows you to encrypt or decrypt arbitrary message using several well known symmetric encryption algorithms such as AES, 3DES, or BLOWFISH. Symmetric ciphers use the same (or very similar from the algorithmic point of view) keys for both encryption and decryption of a message.

I'm writing some software where I have to encrypt all files that are written to a specific folder using AES. There is one password/key that is configured somewhere, that is always used. I don't want to store a base64 string because that is too complicated for the person who might have to change the configuration. I want to encrypt a bunch of strings using openssl. How do I pass plaintext in console to openssl (instead of specifying input file which has plaintext). openssl man page has only these two options Symmetric Ciphers Online allows you to encrypt or decrypt arbitrary message using several well known symmetric encryption algorithms such as AES, 3DES, or BLOWFISH.
