• Using the Environment Variables
To load the FTP SSL-related environment variables, use the following command:

To unset the variable, run the following command:
#unset environment_variable_name
Following are the environment variables in FTP:
FTP_USESSL Specifies if the client enables TLS security mechanism.
FTP_SSL_MODE Specifies the secure mode. If mode is set to tls, the
client sends the AUTH_TLS command to the server. If
mode is set to ssl, the client sends the AUTH_SSL
command to the sever. If mode is set to secure, the client
sends the AUTH_TLS command. If this fails, the client
sends the AUTH_SSL command to the server.

set to 1, peer is verified. By default, the verify flag is
disabled.
FTP_SSL_DEBUG_MODE Specifies if the SSL features must be invoked in debug
mode. If the debug mode is set to 2, extended logging
is performed.
FTP_SSL_NOFALLBACK Specifies if SSL fallback needs to be enabled. By default,
fallback is enabled.
FTP_SSL_PROT Specifies whether the data channel encryption is enabled.
By default, it is enabled.

generator.

FTP_SSL_CONFIG_FILE Specifies the file that contains the configuration options
related to TLS.
FTP_SSL_CERT_FILE Specifies the location of the client's certificate file.
