Extension Maturity Classification: Proposal
Provides a way to specify MD5, SHA1, SHA2 and SHA3 file checksums for assets and links in STAC Items, STAC Catalogs and STAC Collections.
Link Object and Asset Object fields
| Field Name | Type | Description |
|---|---|---|
| checksum:md5 | string | MD5 message-digest algorithm 128-bit checksum for the corresponding file, encoded as hexadecimal string. |
| checksum:sha1 | string | SHA-1 (Secure Hash Algorithm 1) 160-bit checksum for the corresponding file, encoded as hexadecimal string. |
| checksum:sha2 | string | SHA-2 (Secure Hash Algorithm 2) checksum for the corresponding file with varying sizes of 224, 256, 384 or 512 bits, encoded as hexadecimal string. |
| checksum:sha3 | string | SHA-3 (Secure Hash Algorithm 3) checksum for the corresponding file with varying bit sizes, encoded as hexadecimal string. |
Checksum for a text file with file content test.
