uftp_keymgt(1) uftp_keymgt(1) NAME uftp_keymgt - Encrypted UDP based ftp with multicast - key management utility SYNOPSIS uftp_keymgt [ -m ] [ key_file [ key_file ...] ] uftp_keymgt [ -m ] -g key_size key_file uftp_keymgt [ -m ] -d key_file DESCRIPTION uftp_keymgt is a utility for creating, viewing, and deleting RSA pri- vate keys used by the UFTP suite. Although keys can be generated on the fly by uftp(1), uftpd(1), and uftpproxyd(1), this utility gives a more straightforward way of doing so without having to kick off a dummy transfer just to create/view a key. The definition of key_file is dependent on the crypto library UFTP is compiled to use. On Windows systems using the native crypto library (CryptoAPI), all RSA private keys must be stored in a key container (technically only keys used to sign data, but for UFTP's purposes this is the case). Key containers are internal to Windows, and each user (and the system) has its own set of key containers. In this case, key_file is actually the name of the key container. All other systems use OpenSSL for the crypto library (although under Windows UFTP can be also be built to use it). In this case, key_file specifies a file name where the RSA private key is stored unencrypted in PEM format (the OS is expected to protect this file). The -g option is used to generate a key of a given size and store it in the given key_file. The key size and key fingerprint are then printed. Under OpenSSL, a key can actually be generated by the openssl(1) command line utility, although you'll still need to run uftp_keymgt on it to see the fingerprint. The -d option is available only on Windows systems using CryptoAPI. It deletes the key container specified by key_file. When neither -g or -d are specified, the size and fingerprint of all keys listed are printed. If no keys are specified under Windows with CryptoAPI, the private key for all key containers for the current user are printed. Note that some key containers may exist that an applica- tion other than UFTP is using, and some of those may not have an RSA private key. OPTIONS The following options are supported: -g key_size key_file Specifies the size of the key to create in bits and the key_file to store it in. -d key_file Specifies the Windows key container to delete. -m For Windows systems using CryptoAPI, private keys are normally stored in the key container of the running user. Specifying this option stores keys in the system key container. On non- Windows systems, this option has no effect.
