⁠Getting Started

These instructions will cover usage information and for the docker container

⁠Usage

$ docker run --rm bksolutions/htpasswd <parameter>

$ docker run --rm bksolutions/htpasswd:latest <parameter>

⁠Parameter

⁠htpasswd

Usage:

htpasswd [-cimB25dpsDv] [-C cost] [-r rounds] passwordfile username
htpasswd -b[cmB25dpsDv] [-C cost] [-r rounds] passwordfile username password

htpasswd -n[imB25dps] [-C cost] [-r rounds] username
htpasswd -nb[mB25dps] [-C cost] [-r rounds] username password

• -c Create a new file.
• -n Don't update file; display results on stdout.
• -b Use the password from the command line rather than prompting for it.
• -i Read password from stdin without verification (for script usage).
• -m Force MD5 hashing of the password (default).
• -2 Force SHA-256 hashing of the password (secure).
• -5 Force SHA-512 hashing of the password (secure).
• -B Force bcrypt hashing of the password (very secure).
• -C Set the computing time used for the bcrypt algorithm (higher is more secure but slower, default: 5, valid: 4 to 17).
• -r Set the number of rounds used for the SHA-256, SHA-512 algorithms (higher is more secure but slower, default: 5000).
• -d Force CRYPT hashing of the password (8 chars max, insecure).
• -s Force SHA-1 hashing of the password (insecure).
• -p Do not hash the password (plaintext, insecure).
• -D Delete the specified user.
• -v Verify password for the specified user.

⁠Example

⁠Create password

$ docker run --rm bksolutions/htpasswd -B -n -b -C 10  <username> <password>

Docker
