CryptographicHashContent 2.3.0¶
BUNDLE¶
org.apache.nifi | nifi-standard-nar
DESCRIPTION¶
Calculates a cryptographic hash value for the flowfile content using the given algorithm and writes it to an output attribute. Please refer to https://csrc.nist.gov/Projects/Hash-Functions/NIST-Policy-on-Hash-Functions for help to decide which algorithm to use.
INPUT REQUIREMENT¶
REQUIRED
Supports Sensitive Dynamic Properties¶
false
PROPERTIES¶
Property |
Description |
|---|---|
fail_when_empty |
Route to failure if the content is empty. While hashing an empty value is valid, some flows may want to detect empty input. |
hash_algorithm |
The hash algorithm to use. Note that not all of the algorithms available are recommended for use (some are provided for legacy compatibility). There are many things to consider when picking an algorithm; it is recommended to use the most secure algorithm possible. |
RELATIONSHIPS¶
NAME |
DESCRIPTION |
|---|---|
success |
Used for flowfiles that have a hash value added |
failure |
Used for flowfiles that have no content if the ‘fail on empty’ setting is enabled |
WRITES ATTRIBUTES¶
NAME |
DESCRIPTION |
|---|---|
content_<algorithm> |
This processor adds an attribute whose value is the result of hashing the flowfile content. The name of this attribute is specified by the value of the algorithm, e.g. ‘content_SHA-256’. |
