Cryptographic Configuration Manager

A utility module that provides configuration helpers for cryptographic operations, including RSA padding mode selection, elliptic curve point format conversion, and Diffie-Hellman parameter validation.

Capabilities

RSA Padding Mode Selection

• Given the string "OAEP", the getPaddingMode function returns the appropriate numeric constant for OAEP padding @test
• Given the string "PKCS1", the getPaddingMode function returns the appropriate numeric constant for PKCS#1 v1.5 padding @test
• Given the string "PSS", the getPaddingMode function returns the appropriate numeric constant for PSS padding @test

Point Format Conversion

• Given the string "compressed", the getPointFormat function returns the appropriate numeric constant for compressed point format @test
• Given the string "uncompressed", the getPointFormat function returns the appropriate numeric constant for uncompressed point format @test

Diffie-Hellman Validation Helper

• The getDHCheckFlags function returns an object containing all four DH check flag constants with their correct values @test

/**
 * Converts a point format name to its numeric constant value.
 *
 * @param {string} format - The point format name (e.g., "compressed", "uncompressed", "hybrid")
 * @returns {number} The numeric constant representing the point format
