Verificador de hash de arquivo

Escopo e limites

Calcula SHA-256/384/512 dos bytes reais localmente. Sem upload ou histórico. Informe resumo no mesmo formato ou deixe vazio. Hex ignora maiúsculas; Base64 exige preenchimento padrão. A correspondência não prova sozinha editor confiável nem assinatura digital.

Verificador de hash de arquivo

Read a local file in the browser and calculate a SHA-256, SHA-384 or SHA-512 digest from its actual bytes. Choose hexadecimal or Base64 output, optionally enter an expected digest, and compare the values in the same format. The file is processed locally; verify the algorithm and representation before treating a match as evidence of file integrity.

Recursos

  • Read the selected file bytes locally without uploading them.
  • Calculate SHA-256, SHA-384 or SHA-512 digests.
  • View the digest as hexadecimal or Base64 and compare an expected value.
  • Copy or download a report with the file name, size, digest and match result.

Como usar

  1. Select the file you want to verify.
  2. Choose the SHA algorithm and output format.
  3. Enter the expected digest in the same format when available.
  4. Run verification and review or export the report.
