Because the output is a hex string, it should be 96 characters long (2 chars per byte).ĮncStr.s = CkCrypt2:: ckEncryptStringENC(crypt, "The quick brown fox jumps over the lazy dog.")ĭecStr.s = CkCrypt2:: ckDecryptStringENC(crypt,encStr)Ģ000-2023 Chilkat Software, Inc. 44 bytes), so the output should be 48 bytes (a multiple of 16). The input string is 44 ANSI characters (i.e. For 128-bit encryption, the binary secret key is 16 bytes. For 256-bit encryption, the binary secret key is 32 bytes. The secret key must equal the size of the key. It is NOT equal to the length of the key. The length of the IV is equal to the algorithm's block size. An initialization vector is required if using CBC mode. CkCrypt2:: setCkEncodingMode(crypt, "hex") It may be "hex", "url", "base64", or "quoted-printable". EncodingMode specifies the encoding of the output for encryption, and the input for decryption. AES has a block size of 16 bytes, so encrypted output is always a multiple of 16. The padding scheme determines the contents of the bytes that are added to pad the result to a multiple of the encryption algorithm's block size. KeyLength may be 128, 192, 256 CkCrypt2:: setCkKeyLength(crypt, 256) Note: Check the online reference documentation to see the Chilkat versions when certain cipher modes were introduced. CipherMode may be "ecb", "cbc", "ofb", "cfb", "gcm", etc. CkCrypt2:: setCkCryptAlgorithm(crypt, "aes") PureBasic is a commercially distributed procedural computer programming language and integrated development environment based on BASIC and developed by Fantaisie Software for Windows, Linux, and macOS. See Global Unlock Sample for sample code. This example requires the Chilkat API to have been previously unlocked. The Chilkat encryption component supports 128-bit, 192-bit, and 256-bit AES encryption in ECB (Electronic Cookbook), CBC (Cipher-Block Chaining), and other modes. If the user puts more than 32 characters for the password, no error will happen but only the first 32 will count.AES encryption. It's actually reasonably strong, simple as it is.
