Symmetic encryption
For symmetic encryption, you can use the following:
There are multiple ways of generating an encryption key. Most implementations rely on a random object. All examples mentioned here use a secure cryptographic randomizer. AES-256 Encryption with Java and JCEKS. Generate SecretKey. This post has shown how to encrypt and decrypt string based messages using the AES-256 encryption algorithm. The keys to encrypt. SHA256 Hash Generator. This online tool allows you to generate the SHA256 hash of any string. SHA256 is designed by NSA, it's more reliable than SHA1. AES Encryption: Encrypt and decrypt online. The Advanced Encryption Standard (AES), also known by its original name Rijndael is a specification for the encryption of electronic data. It describes a symmetric-key algorithm using the same key for both encrypting and decrypting. Web app offering modular conversion, encoding and encryption online.

Asymmetric encryption
For Asymmetric encryption you must first generate your private key and extract the public key.

Encripting files
Window 7 ultimate product key generator pirate bay torrent. You can't directly encrypt a large file using rsautl. Instead, do the following:
- Generate a key using
openssl rand, e.g.openssl rand 32 -out keyfile. - Encrypt the key file using
openssl rsautl. - Encrypt the data using
openssl enc, using the generated key from step 1. - Package the encrypted key file with the encrypted data. The recipient will need to decrypt the key with their private key, then decrypt the data with the resulting key.
Ultimate solution for safe and high secured encode anyone file in OpenSSL and command-line:

Encrypt text file:
What is what:
smime— ssl command for S/MIME utility (smime(1)).-encrypt— chosen method for file process.-binary— use safe file process. Normally the input message is converted to 'canonical' format as required by the S/MIME specification, this switch disable it. It is necessary for all binary files (like a images, sounds, ZIP archives).-aes-256-cbc— chosen cipher AES in 256 bit for encryption (strong). If not specified 40 bit RC2 is used (very weak). (Supported ciphers).-in plainfile.zip— input file name.-out encrypted.zip.enc— output file name.-outform DER— encode output file as binary. If is not specified, file is encoded by base64 and file size will be increased by 30%.yourSslCertificate.pem— file name of your certificate's. That should be in PEM format.
That command can very effectively a strongly encrypt any file regardless of its size or format.

What is what:
-inform DER— same as-outformabove.-inkey private.key— file name of your private key. That should be in PEM format and can be encrypted by password.-passin pass:your_password— (optional) your password for private key encrypt.
