for decryption. It can be worse, but it cannot be better. There are several excellent encryption algorithms available that could be used. When good encryption is used, attacks are likely to be against the whether you have used weak or strong encryption, the game is over anyway.  Most simple XOR based algorithms can be broken with little effort. Consult a good encryption reference for more information and 2005 G W The section on “Acceptable low security” was reviewed to try and highlight simple XOR algorithms as weak to ensure that readers investigate further if interested in this approach.

Functions 439  • The MD5 and SHA1 algorithms are not recommended for security purposes due to known attacks to generate hash collisions. These two algorithms are provided for backward-compatibility versions. This function fully supports text BLOBs of any length and character set. Supported algorithms not specified When no algorithm is specified, Firebird applies the 64-bit variant of the non-cryptographic ins and outs of the various algorithms are considered beyond the scope of this language reference. We recommend searching the internet for further details on the algorithms. DECRYPT Examples select
