GetHTTP

...

The Deprecated Flow Definition includes GetHTTP configured to retrieve the SHA-256 checksum for the NiFi 1.20.0 distribution. The Flow Definition also includes a required SSL Context Service configured with the Java Runtime cacerts Trust Store.

• GetHTTP-Deprecated.json

The Migrated Flow Definition includes InvokeHTTP configured with the same URL but without the SSL Context Service, which is not required for public trusted HTTPS services.

GetJMSQueue

...

The Deprecated Flow Definition includes GetJMSQueue configured for ActiveMQ running on the localhost address with a specified Destination Name.

• GetJMSQueue-Deprecated.json

The Migrated Flow Definition includes ConsumeJMS configured with a JMSConnectionFactoryProvider using the same JMS broker information. The Migrated Flow Definition includes a JMS Parameters context with a Parameter named JmsClientLibrariesPath referencing the local directory containing the Apache ActiveMQ Artemis libraries.

HashAttribute

Alternatives

Migration

HashAttribute supports generating an MD5 digest of one more FlowFile attribute name and value pairs. The MD5 algorithm is not secure for cryptographic operations, and alternatives such as the SHA-2 or SHA-3 algorithms should be used.

...

Generating a hash attribute from a single FlowFile attribute name and value pair requires the both standard and dynamic properties.

CryptographicHashAttribute uses dynamic properties to specify the source and destination FlowFile attribute names. The Hash Algorithm property should be configured with SHA-256 or other SHA-2 algorithm.

Generating a hash attribute from a single FlowFile attribute value requires both standard and dynamic properties.

Flow Definitions

The Deprecated Flow Definition includes HashAttribute configured to write a FlowFile attribute named label-hash using the label attribute name and the value of the attribute from the incoming FlowFile.

The Migrated Flow Definition includes CryptographicHashAttribute configured to write a FlowFile attribute named label-hash using the value of the label attribute from the incoming FlowFile.

HashContent

Alternatives

Migration

HashContent supports generating a digest of FlowFile content using a configurable algorithm and writing the hash to a specified FlowFile attribute.

CryptographicHashContent supports the same basic digest capabilities and writes the hash to a FlowFile attribute name based on the configured algorithm.

The CryptographicHashContent FlowFile attribute name begins with content. When configured with the SHA-256 algorithm, CryptographicHashContent writes a FlowFile attribute named content_SHA-256.

Both Processors have a Hash Algorithm property, but the CryptographicHashContent Processor supports a scoped set of well-defined algorithms instead of depending on the algorithms that the Java Runtime Security Provider enumerates.

Flow Definitions

The Deprecated Flow Definition includes HashContent configured to write a FlowFile attribute named hash.value using the SHA-256 algorithm.

• HashContent-Deprecated.json

The Migrated Flow Definition includes CryptographicHashContent configured with the SHA-256 algorithm. The Migrated Flow Definition also includes an UpdateAttribute Processor that writes a FlowFile attribute named hash.value using the value of content_SHA-256, providing behavior equivalent to the HashContent Hash Attribute Name property.
