Is OpenSSL encrypt secure?
OpenSSL is a library which has implementations for a variety of cryptographic algorithms, both for strong and for weak algorithms. Thus, the security first depends on which algorithm you use. You are trying to use symmetric encryption where the same key is needed for encryption and decryption.
Is decrypting safe?
Cryptography is used to secure and protect data during communication. Decryption is a process of converting encoded/encrypted data in a form that is readable and understood by a human or a computer. Encryption method helps you to protect your confidential data such as passwords and login id.
How to encrypt files with password using OpenSSL?
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.
How to use ECC to encrypt data in OpenSSL?
Since its so hard to find examples showing how to use ECC to encrypt data I thought I’d post some code for others to use. For the complete listing, check out my openssl-dev posting: Basically its a flushed out usable version of how to use ECDH to secure a block of data. ECDH is used to generate a shared secret.
How to derive an AES key from OpenSSL?
As mentioned in the other answers, previous versions of openssl used a weak key derivation function to derive an AES encryption key from the password.
What’s the difference between GPG and OpenSSL encryption?
Though you have specifically asked about OpenSSL you might want to consider using GPG instead for the purpose of encryption based on this article OpenSSL vs GPG for encrypting off-site backups? To use GPG to do the same you would use the following commands: Note: You will be prompted for a password when encrypting or decrypt.
