0008 exdecrypt - Decrypt the string value

0011 SYNOPSIS
0012 --------
0013 *exdecrypt* STRING [STRING...]
0014
0015
0016 DESCRIPTION
0017 -----------
0018 Program decrypts one or many *STRING* value passed on command line.
0019 In the result program prints to *stdout* clear string value.
0020 The debug is configured in standard way as for all other binaries via
0021 'ndrxdebug.conf' or Common Config.
0022
0023 The encrypted value of the string can be made by *exencrypt(8)* utility.
0024
0025 Encryption keys which are used for string encryption are provided either by using
0026 built-in algorithm (username+hostname) hashed with SHA1.
0027 Or from vendor specific loaded plugin.
0028
0029 The encryption principles allows to encrypt the sensitive data and store on disk
0030 in PCI/DSS compatible way. And *exdecrypt* can be used for scripts to get in
0031 runtime the clear values needed.
0032
0033 In case of decrypt failure, logs needs to be analyzed. There could be problems
0034 with base64 string or invalid encryption key. In case decrypt process founds
0035 the binary zero (0x00 byte) in output string, error is generated automatically,
0036 because this value if forbidden in string decryption.
