This software provides a secure and confidential pipeline to hide sensitive information and data from unauthorized access.
It's important to note that this trick is only effective if the password is deleted from memory and kept in plaintext for as little time as possible. The pipe trick is primarily designed for long-running processes such as mail checkers where the password needs to be used infrequently. The password is stored inside the pipe, which is located in kernel memory space, and can be read back when required.
Although this simple trick is still somewhat effective against attackers, the implementation of SecretPipe is lacking in some areas. There is no way in Perl to ensure that the characters in the string you pass in are securely deleted, which is a weakness that could be exploited by a skilled attacker. To address this limitation, the author of SecretPipe recommends rewriting it in XS and providing a primitive to zero the contents of a string for real.
