From this article you’ll learn how to encrypt … Encrypt and Decrypt File. openssl_encrypt() は、指定した文字列を指定したキーと暗号化メソッドでエンコードされた文字列を返します。暗号化された文字列は openssl_decrypt() で復号化できます。 This is what I have been trying but I'm not having much luck. Sometimes I need to encrypt some stuff but do not want to install PGP or GPG.I typically use OpenSSL for this kind of thing and have written a simple frontend script to achieve strong password based encryption using OpenSSL. 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. PHP Version. Caution. The libcrypto library within OpenSSL provides functions for performing symmetric encryption and decryption operations across a wide range of algorithms and modes. Example 1. And for some reasons openssl_encrypt behave the same strange way with OPENSSL_ZERO_PADDING and OPENSSL_NO_PADDING options: it returns FALSE if encrypted string doesn't divide to the block size.
