From 8da16e55fed6c880a61140e7375eac2e31494f81 Mon Sep 17 00:00:00 2001 From: eyJhb Date: Tue, 27 Aug 2024 19:51:43 +0200 Subject: [PATCH] hash_password accepts stdin now (#17608) `hash_password` now actually accepts password from stdin. The `getpass` reads from TTY, and does NOT accept stdin in any way. The manpage has been updated to reflect that. --- changelog.d/17608.feature | 1 + debian/hash_password.1 | 27 +++-- debian/hash_password.1.html | 182 ++++++++++++++++++++++++++++++ debian/hash_password.ronn | 13 ++- synapse/_scripts/hash_password.py | 4 +- 5 files changed, 216 insertions(+), 11 deletions(-) create mode 100644 changelog.d/17608.feature create mode 100644 debian/hash_password.1.html diff --git a/changelog.d/17608.feature b/changelog.d/17608.feature new file mode 100644 index 000000000..adf9ac553 --- /dev/null +++ b/changelog.d/17608.feature @@ -0,0 +1 @@ +Make `hash_password` accept password input from stdin. \ No newline at end of file diff --git a/debian/hash_password.1 b/debian/hash_password.1 index 39fa3ffcb..af55e09c4 100644 --- a/debian/hash_password.1 +++ b/debian/hash_password.1 @@ -1,10 +1,13 @@ -.\" generated with Ronn-NG/v0.8.0 -.\" http://github.com/apjanke/ronn-ng/tree/0.8.0 -.TH "HASH_PASSWORD" "1" "July 2021" "" "" +.\" generated with Ronn-NG/v0.10.1 +.\" http://github.com/apjanke/ronn-ng/tree/0.10.1 +.TH "HASH_PASSWORD" "1" "August 2024" "" .SH "NAME" \fBhash_password\fR \- Calculate the hash of a new password, so that passwords can be reset .SH "SYNOPSIS" -\fBhash_password\fR [\fB\-p\fR|\fB\-\-password\fR [password]] [\fB\-c\fR|\fB\-\-config\fR \fIfile\fR] +.TS +allbox; +\fBhash_password\fR [\fB\-p\fR \fB\-\-password\fR [password]] [\fB\-c\fR \fB\-\-config\fR \fIfile\fR] +.TE .SH "DESCRIPTION" \fBhash_password\fR calculates the hash of a supplied password using bcrypt\. .P @@ -20,7 +23,7 @@ bcrypt_rounds: 17 password_config: pepper: "random hashing pepper" .SH "OPTIONS" .TP \fB\-p\fR, \fB\-\-password\fR -Read the password form the command line if [password] is supplied\.

NAME

+

+ hash_password - Calculate the hash of a new password, so that passwords can be reset +

+

SYNOPSIS

+ + + + + + + + + +
+hash_password [-p + +--password [password]] [-c + +--config file]
+ +

DESCRIPTION

+ +

hash_password calculates the hash of a supplied password using bcrypt.

+ +

hash_password takes a password as an parameter either on the command line +or the STDIN if not supplied.

+ +

It accepts an YAML file which can be used to specify parameters like the +number of rounds for bcrypt and password_config section having the pepper +value used for the hashing. By default bcrypt_rounds is set to 12.

+ +

The hashed password is written on the STDOUT.

+ +

FILES

+ +

A sample YAML file accepted by hash_password is described below:

+ +

bcrypt_rounds: 17 + password_config: + pepper: "random hashing pepper"

+ +

OPTIONS

+ +
+
+-p, --password +
+
Read the password form the command line if [password] is supplied, or from STDIN. +If not, prompt the user and read the password from the tty prompt. +It is not recommended to type the password on the command line +directly. Use the STDIN instead.
+
+-c, --config +
+
Read the supplied YAML file containing the options bcrypt_rounds +and the password_config section containing the pepper value.
+
+ +

EXAMPLES

+ +

Hash from the command line:

+ +
$ hash_password -p "p@ssw0rd"
+$2b$12$VJNqWQYfsWTEwcELfoSi4Oa8eA17movHqqi8.X8fWFpum7SxZ9MFe
+
+ +

Hash from the stdin:

+ +
$ cat password_file | hash_password
+Password:
+Confirm password:
+$2b$12$AszlvfmJl2esnyhmn8m/kuR2tdXgROWtWxnX.rcuAbM8ErLoUhybG
+
+ +

Hash from the prompt:

+ +
$ hash_password
+Password:
+Confirm password:
+$2b$12$AszlvfmJl2esnyhmn8m/kuR2tdXgROWtWxnX.rcuAbM8ErLoUhybG
+
+ +

Using a config file:

+ +
$ hash_password -c config.yml
+Password:
+Confirm password:
+$2b$12$CwI.wBNr.w3kmiUlV3T5s.GT2wH7uebDCovDrCOh18dFedlANK99O
