Encrypt an EC private key as an encrypted private key (BIP38).

$ bx ec-to-ek --help

Usage: bx ec-to-ek [-hu] [--config VALUE] [--version VALUE] PASSPHRASE   
[EC_PRIVATE_KEY]                                                         

Info: Encrypt an EC private key as an encrypted private key (BIP38).     

Options (named):

-c [--config]        The path to the configuration settings file.        
-h [--help]          Get a description and instructions for this command.
-u [--uncompressed]  Use the uncompressed public key format.             
-v [--version]       The desired payment address version.                

Arguments (positional):

PASSPHRASE           The passphrase for encrypting the private key.      
EC_PRIVATE_KEY       The EC private key to encrypt. If not specified the 
                     key is read from STDIN.

Third party-generated encrypted private keys are referred to as multiplied by BIP-38. To create multiplied encrypted public keys use token-new and ec-new.

The --version option is a libbitcoin enhancement not yet specified in BIP-38.
