. AES ECB. AES-128 AES-256.
The full standard for the CTR-DRBG's is described in the NIST SP 800-90A Rev. The code has a dependency on config.h in the ctrdrbg.c source code file and on aes.h in the ctrdrbg.h header file. You can remove the inclusion of config.h or just create a simple header file to define one or more of the configuration options that the CTRDRBG source code has. Sep 05, 2016 Details for the issue Add support for Delphi FireDAC's SQLite encryption, if it's not too complicated:) It uses aes-256 by default (and it alone will be enough), but supported ciphers are: aes-128, aes-192, aes-256, aes-ctr-128, aes-ctr.

Key. Input Data. Output Data. Encrypt DecryptWhat is AES ECBElectronic Codebook (ECB) mode is the simplest encryption mode in Advanced Encryption Standard (AES).AES is a symmetric-key algorithm i.e. Same key is used to encrypt and decrypt data.
In AES, message is divided into block-size of 128 bits(16 bytes) to perform encryption or decryption operation. AES allows key size of 128, 192 or 256 bits.In ECB, after diving message into blocks of 128 bits, each block is encrypted separately. It’s drawback is, if there are duplicate blocks in input, then encrypted output will be same for duplicated blocks, which gives attacker an advantage to guess the pattern and crack the key and hence the message.ECB is usually used for encrypting small size data. Also, ECB is not recommended for encrypting larger size data.For more details on ECB, refer cscrc.nist.gov.Filed Under.

Note that this encryption uses a global key for the whole process, whichshould match on both Server and Client sides. You should better hard-code thispublic key in your Client and Server Delphi applications, with some variantsdepending on each end-user service. You can useCompressShaAesSetKey as defined in SynCrypto.pas toset globally this Encryption Key, and an optional Initialization Vector.
