Defines a method for digital signature generation and verification for the protection of messages and data using the Digital Signature Algorithm (DSA). This standard is used in conjunction with the hash function, as defined in American National Standard for Public Key Cryptography - Part 2: The Secure Hash Algorithm (SHA-1), BSR X9.30.2. In addition, this standard provides the criteria for the generation of public and private keys that are required by the algorithm and the procedural controls required for the secure use of the algorithm. Specific sections include definitions and common abbreviations, application, the DSA, Generation of Primes for the DSA, Random Number Generation for the DSA.

Produces a 160-bit representation of the message, called the message digest, when a message with a bit length less than 2 to 64th power is input. The message digest is used during the generation of a signature for the message. The message digest is computed during the generation of a signature for the message. The SHA-1 is also used to compute a message digest for the received version of the message during the process of verifying the signature. Any change to the message in transit will, with a very high probability, result in a different messages digest, and the signature will fail to verify. The Secure Hash Algorithm (SHA-1) described in this standard is required for use with the Digital Signature Algorithm and may be used whenever a secure hash algorithm is required.

Describes the carriage of some forms of timed text and subtitle streams in files based on ISO/IEC 14496-12 (the ISO base media file format). The documentation of these forms does not preclude other definition of carriage of timed text or subtitles; see, for example, 3GPP Timed Text (3GPP TS 26.245), or the carriage of captioning information embedded in a media stream of another type (see Annex A).
