hash algorithm(s) used. The hash algorithm(s) used for computing those hash digest(s) shall be a
cryptographically strong one(s), in common use, and not subject to publicly disclosed weaknesses such
as collisions (for example, SHA-512, SHA3-512, BLAKE2 or RIPEMD-160, but potentially a stronger
one, depending on technological developments);
(b) where applicable, shall indicate as part of the manifest referred to in point (a) above the date and time until
which the electronic evidence will remain accessible. This period shall provide the competent authority in the
issuing State with a reasonable timeframe to retrieve the electronic evidence, which shall be no less than 10
calendar days and no more than 45 calendar days from the moment the electronic evidence is made available.
At the request of the competent authority of the issuing State, the period indicated by the originator may be
extended in an individual case;
(c) may record and transmit any additional information or remarks relevant to the case to the authority to which
the electronic evidence has been transmitted or made available, as part of the manifest referred to in point (a)
above.

programmatically collect, transmit or otherwise provide access to the statistics referenced in paragraph 2 of that
Article in both structured (e.g., XML) and unstructured (e.g., PDF) data formats. In accordance with Article 28(3) of
Regulation (EU) 2023/1543, where technically equipped, national portals(3) operated by Member States may also
transmit or provide these statistics to the Commission through an automated process. The Commission shall issue
guidance on the data structure and the method for collecting and communicating these statistics.
(1) For greater clarity, references to competent national authorities shall, mutatis mutandis, also be understood as applying to Eurojust
national members, European Prosecutors, and European Delegated Prosecutors, insofar as they are empowered to perform the same
functions under EU law and national law.
(2) It should be recalled that in accordance with Article 19(5) transmission through such alternative means of communication shall meet
the requirements of being swift, secure and reliable, allowing the recipient to establish authenticity.
(3) ‘National portals’ should be understood as national ‘IT systems’ that form part of the decentralised IT system, as defined in Article 3(21)
of Regulation (EU) 2023/1543.
