Functional Requirements

Hash Computation from Byte Data		status: valid security: YES safety: ASIL_B
reqtype: Functional version: 1 derived from: feat_req__baselibs__hash_library satisfied by: comp__baselibs_hash
The hash library shall compute a hash value over a contiguous byte sequence supplied by the caller, accumulating state across one or more data inputs and producing the final digest upon finalization.
comp_req__hash__calculation_interface		Component Requirement

Hash Value Retrieval as Raw Bytes		status: valid security: YES safety: ASIL_B
reqtype: Functional version: 1 derived from: feat_req__baselibs__hash_library satisfied by: comp__baselibs_hash
The hash library shall expose the computed hash value as a raw byte sequence.
comp_req__hash__value_retrieval_bytes		Component Requirement

Hash Value Retrieval as Hexadecimal String		status: valid security: YES safety: ASIL_B
reqtype: Functional version: 1 derived from: feat_req__baselibs__hash_library satisfied by: comp__baselibs_hash
The hash library shall expose the computed hash value as a hexadecimal string representation.
comp_req__hash__value_retrieval_hex		Component Requirement

Algorithm Selection via Factory		status: valid security: YES safety: ASIL_B
reqtype: Functional version: 1 derived from: feat_req__baselibs__hash_library satisfied by: comp__baselibs_hash
The hash library shall allow the hash algorithm to be selected and a calculator instance to be created independently of the code that performs the computation, so that the calling code is not coupled to any specific algorithm implementation.
comp_req__hash__factory_interface		Component Requirement

Cryptographic Hash Algorithms		status: valid security: YES safety: ASIL_B
reqtype: Functional version: 1 derived from: feat_req__baselibs__hash_library satisfied by: comp__baselibs_hash
The hash library shall support SHA-1, SHA-256, SHA-384, and SHA-512 as cryptographic hash algorithms.
comp_req__hash__sha_algorithms		Component Requirement

CRC-32 Checksum Algorithm		status: valid security: YES safety: ASIL_B
reqtype: Functional version: 1 derived from: feat_req__baselibs__hash_library satisfied by: comp__baselibs_hash
The hash library shall support IEEE CRC-32 as a checksum algorithm.
comp_req__hash__crc32_algorithm		Component Requirement

Exception-Free Error Propagation		status: valid security: YES safety: ASIL_B
reqtype: Functional version: 1 derived from: feat_req__baselibs__hash_library satisfied by: comp__baselibs_hash
The hash library shall propagate errors from hash calculator instantiation via return-value types, enabling use in safety-critical contexts where exception handling is not available.
