MySQLのAES_ENCRYPT/AES_DECRYPT互換の方式でActiveRecordの属性を透過的に暗号化/復号するRubyMySQLActiveRecord Ruby on Rails (DBはMySQL) で開発をしている某案件で 運用の都合上、アプリ外から SQL でデータベースの内容を直接参照できる必要があるので、センシティブなデータは AES_ENCRYPT 関数で暗号化して、アプリ以外からも復号できるようにすること という要件がありました。 単に暗号化すればいいだけなら attr_encrypted gem などを使って透過的に Ruby 側で暗号化/復号すれば楽に実装できますが、いちいち MySQL 側で AES_ENCRYPT/AES_DECRYPT させるとなると、かなり実装が面倒です。 そこで、Ruby 側で MySQL の AES_ENCRYPT/AES_D

cryptico.js cryptico-min.js documentation Generating an RSA key pair & public key string Sam wants to send Matt an encrypted message. In order to do this, he first needs Matt's public key string. A public key pair can be generated for Matt like this: // The passphrase used to repeatably generate this RSA key. var PassPhrase = "The Moon is a Harsh Mistress."; // The length of the RSA key, in bits.
Java Simplified EncryptionJasypt is a java library which allows the developer to add basic encryption capabilities to his/her projects with minimum effort, and without the need of having deep knowledge on how cryptography works. High-security, standards-based encryption techniques, both for unidirectional and bidirectional encryption. Encrypt passwords, texts, numbers, binaries...Transparent integ
